WELCOME!

Welcome to the incredible world of insects!

Did you know that scientists have identified over a million ins species, and they think ther e may be millions more still to ect find? These tiny animals are vital for supporting life on Earth, but their numbers are in decline so it’s really important that we learn about their habits and try to protect them. Inside this iss ue you’ll find lots of ideas for ob serving bugs without harming them – maybe you’ll find a new sp ecies! You can also get busy making fluttering butterflies, flapping moths and cuddly sock insects!

NASA is sending a spacecraft to Europa in 2024 to investigate whether it could harbour extra-terrestrial life.

Jupiter’s moon Europa has a vast ocean hidden beneath its icy crust. It is thought to be one of the best places in the solar system to look for extra-terrestrial life. Now computer modelling has suggested that the rocky layer beneath the ocean could be hot enough to melt, creating volcanoes on the ocean floor. The researchers think Europa’s internal heat could be caused by the massive gravitational pull of Jupiter. This would make Europa’s interior move, creating heat in the same way that repeatedly bending a paperclip makes it feel hot. Underwater volcanoes could mean there are hydrothermal vents on the seafloor, like the ones on Earth where life is thought to have started.

Move over Dr Dolittle! Scientists are using AI to decode communication between animals. Being able to understand other animals might make us treat them with the respect they deserve. However, some scientists think that even if we could translate what animals are saying to each other, we could never communicate with them because our minds work in such different ways. AI systems using the same technology as Google Translate could enable researchers to translate animal communication without having to understand the way they think. So, although you probably won’t be able to chat with your dog in the near future, humans might soon be able to communicate with other highly intelligent species like apes. What would you ask them?

Scientists at the British Ecological Society are investigating natural ways to reduce carbon dioxide in the air following the UK government’s pledge to cut carbon emissions. In addition to planting trees, they think that restoring damaged peat bogs could have a big impact. Peat is a kind of soil that forms over millions of years from partially rotted plants. It is estimated that peat bogs contain three times as much carbon as forests. But when peat is dug up and burnt or used in gardens, that carbon is released into the atmosphere. Preserving peat bogs and keeping them wet could dramatically reduce carbon emissions.

Sharks use ‘magnetic maps’ to navigate

Some shark species travel thousands of kilometres and return to specific locations each year. New research has shown that, like turtles, they seem to be using Earth’s magnetic field to find their way across the ocean. Scientists at Florida State University tested how wild sharks in a tank behaved when exposed to magnetic fields mimicking specific locations. They found that the sharks swam in the direction of their homes, suggesting that they were using the magnetic field like a map. “It’s nature’s GPS,” said project leader Bryan Keller. “How cool is it that a shark can swim a 20,000 km round trip in a three-dimensional ocean and get back to the same site? It really is mind blowing.”

COULD PEAT BOGS HELP SAVE THE WORLD?

© Gerry Bishop / Shutterstock.com

This spring, eastern US states were invaded by billions of creatures from underground. ‘Brood X’ is a group of periodic cicadas with a 17-year life cycle. These insects spend 17 years underground feeding on plant roots before resurfacing. Once the nymphs have emerged from their tunnels, they shed their skin, dry off, then set about looking for a mate. To attract a female, the males produce an ear-splitting mating call that can reach 100 dB – loud enough to damage your ears! By the middle of July, they will all have died. But the millions of eggs they have hidden in trees will soon hatch and the newborn nymphs will burrow underground for another 17 years. How old will you be when they next see daylight?

Book lice live in old books!

Insects may be small, but there are a LOT of them – and they live almost everywhere. You’ll find them in parks and gardens, forests, deserts, under the ground and sharing our homes.

Some people are scared of insects, or don’t like them. And it’s true that a few can bite or sting. But insects are amazing – beautiful, interesting, weird and wonderful. And incredibly important too.

Make your own pooter!

Spineless Insects belong to the invertebrates, a group of animals that don’t have vertebrae (backbones). In fact, they don’t have bones at all. They have a tough outer skin or shell instead, called an exoskeleton. Besides insects, invertebrates include spiders, centipedes, worms, slugs and snails.

What’s a pooter? It’s a handy device for collecting insects, so that you can look at them without touching or harming them.

You will need: • A clear plastic tub with a lid, such as a clean, dry hummus pot • Sticky tape • A ballpoint pen • Modelling clay or sticky tack

• Scissors • A paper straw (the wider the better), or make one by rolling up and taping thin card • Some old, thin tights or muslin

What you do: 1. Make a hole in each side of the tub by pushing the pen through the plastic into a large lump of modelling clay or sticky tack. 2. Cut the straw in half and push one half into one of the holes, holding it in place with sticky tack if necessary. 3. Cut 2-3 cm off the other half of the straw, put to one side and cut a 2-cm-long slit down one side of the piece that’s left. Push this through the other hole in the tub (slit end first).

Insect sorter Only four of these creepy-crawlies are insects. The others crept onto the page when we weren’t looking! Can you spot all four insects? Put a tick by their names. Check your answers on page 34. 1. Dragonfly

5. Earwig

2. Butterfly

6. Earthworm

3. Woodlouse

7. Stick insect

4. Scorpion

8. Spider

4. Cut out a small piece of fabric from the tights or muslin, about 3 cm x 3 cm. Cover the slit end of the straw with the fabric, then push the 2 cm section over it to hold it on (the slit should make this section narrower, so that it fits inside). Replace the lid.

5. To catch small insects, point the uncovered straw at the insect and suck gently on the other straw to pull it into the tub.

Remember to set us free after you’ve had a good look!

The pooter is named after American entomologist (insect scientist) Dr William Poos! He invented it in the 1920s.

Insect shapes and sizes

Dragonflies and damselflies

Did you know that there are over a MILLION different species (types) of insects? Here are just some of the main insect groups…

Long wings and tail

Beetles

Cranefly

Hard wing-covers

Bees, wasps, ants and termites

Halteres help to stabilise flight

Butterflies and moths

Stick insects Look like twigs or leaves

Large colourful or patterned wings

Grasshoppers Strong back legs for hopping

Lice

Mantids Big front legs

Bugs

And there could be millions more insect species we haven’t even discovered yet!

Flies

Up in the air Many insects have wings and can fly, like bees, wasps, moths, locusts and ladybirds. And, of course, flies! Insect wings are very thin and light, but they have a network of veins that give them strength. The buzzing sound some insects make comes from their wings beating fast. Some insects, like bees and butterflies, have two pairs of wings. Butterflies and moths have tiny scales on their wings, which give them their colours and patterns. Others only have one pair of wings. Flies, like this cranefly, have two wings and two little sticks called halteres, which help them keep their balance when they’re flying.

Bugs on a tray

The clue’s in the name!

Try this quick and easy way to have a look at some insects. Put a piece of white paper on a baking tray and hold it under a bush or low tree branch. Ask someone else to give the bush or branch a shake, and some creepy-crawlies should fall out! See if you can spot which ones are insects. (Tip them back onto the branch or bush afterwards.)

No wings needed! Some insects can’t fly at all, and get around in other ways. Instead of wings, fleas have big, strong back legs to help them make giant leaps!

How do you start an insect race? One, two, flea, go!


you n ce? o, o!

What do you call a fly with no wings? A walk!

Like other living things, insects have babies – but baby insects can look very unlike their parents. Many types of insects go through a metamorphosis, or change of shape, as part of their life cycle.

Life cycles Tree bark bugs Many insects live under tree bark. Try tying a piece of cardboard (about 30 cm x 45 cm) to a big tree in the evening and see if there’s anything underneath it the next morning. Before you untie your trap, hold your bug tray underneath to catch any that might fall. You could compare the insects you collect from different kinds of tree. Wiping a bit of peanut butter or honey on the ‘tree side’ of the cardboard might help to attract more insects.

Pupa

After feeding and growing, the larva becomes a hard pupa. Inside, it changes into an adult (metamorphosis).

Some midges (tiny flies) can beat their wings more than 1,000 times a second.

The larva isn’t much smaller than an adult ladybird, but it looks very different!

Whose baby? Can you match these insects to their babies? Check your answers on page 34.

Mini me However, some baby insects do look like their parents – earwigs, for example, lay eggs and tiny mini earwigs (called nymphs) hatch out!

Wait for me mum!

Insect movie stars Making a slow-motion video is a brilliant way to get a better look at an insect in your pooter, or on a bug tray. Ask to borrow a smartphone from an adult and select the slo-mo video option in the camera settings. Zoom in on your insect and record a short video. Then you can play it back and see much more clearly how the insect moves.

WE NEED INSECTS! Insects are a vital part of nature and do many important and useful things.

What is an insect’s favourite subject? Mothematics!

They are food! The billions of insects all over our planet are an important food source for other animals. Spiders, birds, bats, lizards, fish, bears and many other animals – even other insects – all depend on having insect prey to catch and eat.

They pollinate plants! When honeybees fly from one flower to another, feeding on nectar, they spread pollen between flowers too. Flowering plants need to share pollen to help them make seeds. In fact, many other insects do this too, including some types of flies, butterflies, moths and beetles.

They’re great recyclers!

Make your own sweep net! Entomologists use sweep nets to collect insects from long grass. You can make your own using an old pillowcase, a bamboo cane and a coat hanger.

Many types of insects are decomposers. This means they feed on dead plants and animals, or on animal poo. It ends up as insect poo, which becomes part of the soil, making it healthy and fertile so that new plants can grow. Dung beetles feed on animal dung

What you do: 1. Pull a coat hanger into a circle shape and straighten out the hook. You may need an adult to help you. 2. Pass the open end of a pillowcase through the circle and fold the edges over it. 3. Fix the two layers of fabric together with a stapler or strong tape.

Come out and say hi! Insects love to hide in soil and leaf litter (old, dead leaves). You can get them to come out, without squashing or harming them, using a Berlese funnel.

You will need: 4. Push the straightened hook into the bamboo cane if it’s hollow, or lay it alongside it if not. Use strong tape to secure the handle in place. 5. Walk through long grass on a warm day, sweeping the net from side to side, and see how many insects you can catch! Release them back into the grass afterwards.

• A large plastic bottle or milk carton, washed out and dried • Soil or leaf litter (or a bit of both)

• A trowel or spade • A bright desk lamp or warm, sunny windowsill • Scissors

Food chains

Insects in trouble

All living things need energy to live. Food chains show the flow of energy from one living thing to another. Plants make their food using energy from the Sun. Animals eat plants and other animals eat them! Insects play an important role in many food chains. Without them, many bigger animals would starve.

Sadly, the number of insects is falling, and some species are dying out. Bees, butterflies and moths are especially at risk. Turning wild areas into cities and farmland removes insect habitats, so they have nowhere to live. Using pesticides (bug-killing chemicals) to kill insects is another cause.

Rosebush Producer

Aphid Primary consumer (Prey)

Ladybird Secondary consumer (Predator)

What you do: 1. Ask an adult to help you cut the bottle or carton in half, like this.

Robin Tertiary consumer (Predator)

What can you do? Luckily, there are ways you can help insects…

2. Turn the top half over to make a funnel, and fit it into the bottom half.

• If you have a garden, let part of it grow wild to give insects a place to live.

3. Use the spade to collect soil or leaf litter, or a mixture, and put some into the funnel so it’s about 5 cm deep.

• Don’t use insect-killing sprays.

4. Put the funnel on a very sunny windowsill or stand it under a bright desk lamp that feels warm when it’s switched on. 5. The heat and light will make insects burrow deeper down, until they drop out into the container at the bottom. After a few hours, remove the top part of the funnel so you can have a look. Make sure you put the insects and soil back where you found them afterwards, and wash your hands.

• Choose organic food if you can, as it’s grown without using dangerous pesticides.

Thanks!

Ants

Ants are a massive group of insect species that are related to wasps and bees. There are up to 22,000 different species that live all over the planet, except Antarctica and a few isolated islands.

This month, with magnifying glass in hand, our vet Joe Inglis is peering into the micro-sized world of the ultimate social insect.

Ants breathe through their skin.

Super social Although each individual ant is small, often just a few millimetres in length, their families can be super-sized. Ants live in groups called colonies, which can range from 30 or 40 individuals right up to many millions living together. These colonies are known as super-organisms because they work together almost like a single creature for the good of the whole colony.

Colossal colonies Some ant colonies can be mind-bogglingly big – the largest found so far is an amazing 3,700 miles wide! It is a connected super-colony in southern Europe made up of millions of nests and billions of ants of a species called Argentine ants.

6 cm

Fungi farmers Some species of ants live in sophisticated farming colonies. These ants collect leaves and feed them to specialised fungi that they carefully cultivate in underground chambers. Ants started farming around 60 million years ago – way before humans thought up the idea!

Work, work, work! Several different types of ant live inside an ant colony. The biggest group are workers, which are usually females that can’t breed and spend their lives finding and fetching food for the colony. Fertile male ants are called drones, and there are usually one or more fertile queen ants (who mainly eat food and lay eggs).

The length of queen driver ants, which are the largest ants in the world


Like all insects, ants have their skeletons on the outside of their bodies, not the inside. These tough outer layers are called exoskeletons, and they support and protect their internal organs.

Eye spy To find their way around, ants have eyes made up of lots of tiny lenses joined together. These are called compound eyes and they‘re good for spotting movement, but not so good for studying things in fine detail. (That’s why you’ve never seen an ant read a book!)

I saw a fantastic film about a very large insect. It was XL ant!

Armour plated

Touchy feely Ants have two long feelers, or antennae, which sense for chemicals in the air and feel air currents and vibrations. They also use their feelers to talk to each other, passing on messages by touching feelers together. © Achkin / Shutterstock.com

Bite the bullet! Despite their tiny size, ants can be ferocious creatures. Many species have super-powerful bites and toxic stings, which they use for killing prey and for defence. The bullet ant of Central and South America is thought to have the most painful sting of any insect in the world!

Can you think of five other animals with the word ant in their names? Here’s one example: cormorant. Write any you think of here and check them on page 34.

Find a way through the dragonfly wing maze. Check your answer on page 34.

friendly and love e I’m to be part of a team

ANSWERS

a) Always buzzing about, you’re a brilliant bee. The garden bumblebee’s tongue can be as long as its own body! At up to 2 cm, it is the longest tongue of all UK bumblebees. b) Cool and self-reliant, you’re a dynamic dragonfly.

f

I’m independent and patient

Dragonflies catch their insect prey in mid-air, grabbing it with their legs. They often eat it while still in flight. Adult dragonflies can see some colours that we can’t, such as ultraviolet. c) Always popular, you’re a loveable ladybird. Ladybirds are awesome predators. A single ladybird can eat an average of 5,000 aphids during its lifetime. d) A real bright spark, you’re a glow worm. Female glow worms climb up onto plants and emit a greeny-orange light from their rear ends to attract males. Glow worm larvae and eggs can also emit light.

g

I’m creative and resourceful

e) Everyone’s best friend, you’re an awesome ant. Ants love sweet treats but are omnivorous, meaning they will eat anything from fruit to other ants. Ants don’t have ears – they ‘hear’ by feeling vibrations through their feet. f) Quick and decisive, you’re a plucky pond skater.

I love to make h some noise!

Common pond skaters have water-repellent hairs on the bottom of their feet, which allow them to walk on the surface film of water. They hunt smaller insects by detecting vibrations in the film and then stab their prey with their sharp mouthparts. g) A master of disguise, you’re a majestic moth. Many moths have extraordinary camouflage skills, while others can be brightly coloured. Some moths can make high-pitched, ultrasonic squeaks to jam the sonar of bats which hunt them. h) You’re a groovy grasshopper. Male meadow grasshoppers make chirping sounds by rubbing little ‘pegs’ on their legs across their forewings. They are the UK’s only flightless grasshopper, as they have no hindwings.

MAKE A SOCK INSECT Save an old sock from landfill by turning it into a cuddly insect! Your insect should have a head, thorax, abdomen and six legs.

You will need: • An old sock • 5 pipe cleaners or • Stuffing – use the 20- cm lengths of inside of an old pillow, coated garden wire cotton wool, or cut • Scissors ripped or stained Optional: clothes into thin strips • But tons for eyes • 3 small elastic bands • Fabric glue or 20- cm lengths of • Felt or other scraps yarn or thread of fabric

PULLOUT INSECTS

PULL OUT PAGES 17-20 AND GET MAKING!

FLUTTERING BUTTERFLIES! You will need:

What you do:

• • • • •

The butterfly wings templates • A paperclip (3 cm long) • A small elastic band, Scissors such as a loom band or Sticky tape mini rubber hairband Pliers A safety pin (about 4 cm long)

1. Cut out the wing templates. 2. Ask an adult to bend the bottom part of a safety pin 90 degrees using pliers.

3. Open out the paperclip. Ask an adult to bend it around a paintbrush handle or skewer to make a small loop in the middle. Check the loop is small enough to fit through the round hole at the bottom of the safety pin.

4. Thread the rubber band onto the wire loop, then push the other end of the band through the hole at the bottom of the safety pin.

5. Hook the other end of the rubber band over the catch of the safety pin.

6. Attach the paper templates to the wire and safety pin with sticky tape as shown in the photo at the top of the page. 7. Spin the wire and wings (about 20 times) to twist the rubber band, hold it up and then let go!

Colour in these wings with your own design!


You should find: The butterfly flies away! As you wind up the rubber band, you store energy. As the rubber band unwinds, this energy is released, spinning the wings. As they spin, the wings push against the surrounding air, creating thrust and lift. The faster they spin, the more thrust and lift they get.Test your butterfly’s flying abilities. See what happens if you change the number of times you twist the rubber band. You could also try changing the angle of the front wings by bending the paperclip more or less.

The moth template Scissors Hot glue gun or strong glue Clothes peg Piece of card

What you do: 1. Cut out the template. 2. Fold the wings up slightly as shown.

3. Cut two strips of card, measuring about 4 cm x 1 cm. Attach the strips to the wings as shown.

4. Ask an adult to use a hot glue gun or strong glue to stick the moth to the top of the peg and the strips to the lower part of the peg.

5. When the glue is dry, open and close the peg to make the moth flap its wings!

The atlas moth is the biggest moth in the world, with a wingspan of up to 27 cm – that’s wider than an adult’s hand! Their caterpillars eat huge quantities of leaves but once they have transformed into an adult moth, they do not feed at all and live for only a week or two.

Interview with a SCIENCE HERO

In my job I get to... dig in poo to find dung beetles!

Darren is a dung beetle expert who looks after a huge collection of insects. If you have any questions of your own for Darren, you can contact him on darren.mann@oum.ox.ac.uk

I knew I wanted to be a museum entomologist when I was at school.

My teacher let me play with the cockroaches and newts that were kept in my classroom.

I’ve always loved the natural world, and preferred sitting in a field to a classroom. When I was younger, all I did was read about cockroaches – I had dozens of cages of live cockroaches from across the world. My older sister still hasn’t forgiven me for when she found a hissing cockroach inside her boot! Sadly, there are few wild cockroaches in Britain. I soon got bored of hunting for them as I never found any! I switched to looking for pest species, and once got thrown out of a shop for catching German cockroaches. The owner was unhappy with me, jar in hand, chasing cockroaches around his shop, especially in front of the other customers.

My teachers didn’t support my dream – I was even told there was no such job! Many of my friends did work experience in factories, but I managed to get a two-week placement in a museum’s natural history department. I had to copy out information about hoverflies. Even though I didn’t enjoy English or handwriting, and I couldn’t say the scientific names, copying out these fly facts was fascinating. I continued to volunteer after school and during the holidays. I learned how to use a microscope, how to preserve insects and moved a beetle collection from old store boxes to a new cabinet. It was so satisfying!

s in cowpats! Darren hunts for dung beetle


Interview with a SCIENCE HERO

When I was very young, I loved skidding through wet cow pats in my wellies!

I saw beetles fleeing and years later, as my beetle interest grew, I wanted to know what those species were. I collected a few, took them to the museum and identified them. I spent hours searching dung, finding beetles, and identifying them – including some quite rare ones. Later, I started working at Oxford University Museum of Natural History and became interested in dung beetles from exotic places. There are dung beetles that eat meat, vegan dung beetles, and some that hunt millipedes. There are rollers, tunnellers and dwellers. They improve soil health, plant seeds as they bury dung and are important recyclers in many ecosystems. I will never run out of beetles to look at!

Dung beetles come in all shapes, colours and sizes, including this monster, Coprophananeus lancifer.

I’m so lucky that my childhood hobby has become my career.

I’ve crawled through every single part of the Oxford Museum looking for pests.

My work isn’t just about looking after museum collections – I’ve searched from the basement to the attic looking for insects that can harm or even destroy a collection surprisingly fast. We’re working on a major project at the moment: moving over one million insects into new storerooms in shiny new pest-proof cabinets. First, we spent many hours working on funding applications to raise money for staff and equipment. Then we counted, catalogued, photographed and moved the insects. My job is to sort part of the beetle collection. Moving a specimen from an old cork-lined drawer, labelling it, and transferring it to the new tray takes a steady hand. Some of our insects are over 100 years old so require cleaning or repair. When the specimen is labelled and in its species tray, it looks fabulous!

Even though I didn’t work so well at school, I was dedicated to entomology and spent all my spare time studying, reading, collecting and identifying insects – and it paid off. Qualifications are important, but enthusiasm, knowledge and experience in your chosen field are equally as important. Volunteering gained me lots of experience both working with collections and insect identification, most of which isn’t taught at school or university. I doubt I would be where I am today if I had not been given that opportunity to volunteer all those years ago. Read some more about Darren’s incredible work here: bit.ly/2QyWb9n

Gears

HOW STUFF

WORKS 8

7

6

Gears are used in many technologies, from clocks to racing cars. They allow us to massively increase and control the power we can exert through machines. Bikes use gears – and here’s how they work…

The rear derailleur also has two small gears called the idler and jockey gears. These are held in place by a powerful spring. They keep the chain tight whatever combination of gears the rider selects.

There are up to 11 different gears on the rear cassette, and they work in the opposite way to the front gears. Moving from a large gear with lots of teeth to a smaller one makes the bike go faster because for every pedal stroke the chain will turn a small gear more times than a larger one.

At the back wheel, the chain runs through the rear derailleur. Like the front mechanism, this also allows the rider to shift between gears and change how far the bicycle will move for every pedal stroke.

For many years, scientists thought that gears were a completely human invention, but a recent discovery has shown that evolution got there first. A 3-mm-long hopping insect named Issus coleoptratus has cog-like strips of intermeshing teeth built into its back leg joints. These rotate like mechanical gears to ensure both back legs move at exactly the same time when the insect jumps.

Before the invention of derailleur bicycle gears around 100 years ago, racing bikes only had two gears, one on each side of the back wheel. To change gear riders had to stop, remove the back wheel, turn it around and put it back on!

Gear shifters are the controls

the rider uses to shift gears. They are usually located on the handlebars with cables inside the bike’s frame that connect them to the derailleurs.

5

By moving from a big chain ring, which has lots of teeth, to a small chain ring which has fewer, the rider will move the chain less distance with each pedal stroke. This means the bicycle moves more slowly, but with more power. This helps riders climb up steep hills.

Pedals, which are connected to a central bearing by a crank arm, convert the rider’s leg power into rotational movement.

The crank arms connect the pedals to one or more large gears called chain rings.

4

On bikes with more than one chain ring, a device called the front derailleur allows the rider to move the chain between the chain rings – either via a mechanical cable or using an electronic shifter.

3

The teeth of the chain ring gear lock into the chain, which transfers the pedal power to the back wheel.

The incredible golden tortoise beetle looks like, well, a tiny golden tortoise! It is actually a leaf beetle that can rapidly change colour when disturbed, looking more like a ladybird. The larvae protect themselves by attaching a ‘faecal shield’ (a pile of poo) to their backs.

It’s hard to tell which is the front end of the bizarre-looking saddleback caterpillar! These slug moth larvae are found in North America and Mexico and are covered in venomous hairs.

This might look like a thorny branch, but it’s actually a load of thorn bugs! These treehopper insects disguise themselves as thorns to stop birds from eating them.

It’s easy to guess how giraffe-necked weevils got their name. These Madagascan insects use their long necks for fighting. They also help the weevils to build protective egg cases from leaves.

4

This scary-looking individual is a spiny devil katydid. It’s a herbivore that lives in the rainforests of North and South America. Its spines evolved to make it harder for predators to eat it.

This planthopper nymph might look like its bottom is exploding, but these are actually waxy filaments produced by the insect. Scientists aren’t sure why they do this, but it could be to distract predators.

The huge Atlas moth has wing tips that look like a cobra about to strike. It uses these to scare away predators.

Strike a pose! The devil’s flower mantis mimics an orchid flower to lure prey. When threatened, it adopts this defensive position. Female mantises often eat the males after mating!

Glow worms are actually the larvae of some species of beetles and gnats that glow at night because of bioluminescent enzymes produced in their abdomens. They use the light to attract mates.

The puss moth caterpillar is enough to give children nightmares! Its horror-movie face is actually a trick – its real head is hidden inside the gaping ‘mouth’. And if that doesn’t work, it can also spray acid from its rear end.

Sensational Scientists

MARGARET S. COLLINS By Claire Cock-Starkey

Nicknamed the ‘Termite Lady’, Margaret S. Collins was the first female African-American entomologist (insect scientist) and an important campaigner for civil rights.

L I NS S . C OL , A R ET G TUTE I R T A M I N I NS USA N R O WA S B V I RGI N I A , W E ST 2. I N 192

Margaret grew up in West Virginia, a southern US state where the racist laws of the time kept black people and white people segregated. This meant that there were separate public facilities, such as buses, schools, universities and drinking fountains, for black people.

Her father was a professor of agriculture at West Virginia State College, a university set up to provide education for African-Americans. The college had a thriving intellectual community, which encouraged Margaret to pursue her academic dreams.

From a very young age, Margaret had an extremely inquisitive nature and she was considered a child prodigy. As a result, she was given access to the college library from the age of six. She progressed so quickly that she was allowed to attend the college as a student aged just 14.

During work on her PhD, Margaret met termite expert Alfred Emerson. He helped to guide her research, but he discouraged her from working in the field. Instead, she focused her research on the world’s largest collection of termites kept at Emerson’s lab.

Women are too troublesome to go on field trips.


As her career progre ssed, Margaret was finally free to go on field trips, which she relished. Sh e observed termites in the wild in places such as the Sonoran Desert in Arizona, Mexico, Belize, Guyana and th e Caribbean.

Margaret published over 40 scientific articles on her research, adding a huge amount to our understanding of termites, from how they survive in hot, dry climates to how to use termite waste to strengthen building materials.

How many termites can you spot in this scene? Check your answer on page 34. Alongside her academic work, Margaret championed the fight for equalit y as part of the civil rights movement. In 195 6, two black students called for a boycott of the buses in Tallahassee after they were arrested for refusing to sit in the seats at the back of the bus reserved for black peo ple. Margaret joined the protest and volunteer ed to drive a bus to get black students and academics involved in the protest to colleg e.

Margaret taught as a professor at three different universities and was also named President of the Entomological Society. She was an inspiring teacher and continued to support her students even after they’d graduated, helping others to excel in the field.

Her love of science and her commitment to the civil rights movement were combined when Margaret organised a prestigious symposium for the American Association for the Advancement of Science on Science and the Question of Human Equality.

Margaret’s academic achievements would be extremely impressive today, but to have achieved all she did during an era of widespread sexism and racism makes her accomplishments even more remarkable. To honour her huge contribution to the field, the Smithsonian National Museum of Natural History named a collection of termites after her.

In the 1860s, chemist August Kekulé was puzzling over the shape of a benzene molecule. He knew it couldn’t be a straight line because the chemistry just didn’t work.

The orangey-red on your robin is made by a group of pigments (colour molecules) called melanins. These also give human skin and hair its different colours. Birds evolve colourful feathers for lots of different reasons, from camouflage to attracting a mate. Robins are very territorial, and their red breasts are a sign of their strength and survival skills. Every year, male robins’ red breasts get a bit bigger, warning younger robins not to challenge them and signalling to females that they have good genes and would make a good mate.

Surprisingly, balloons are not airtight. The high pressure inside a balloon pushes air out of microscopic holes in the walls and knot, so it gradually deflates. Helium is smaller than air molecules, so it escapes more quickly. Shiny mylar balloons are more airtight and not under high pressure… but helium can still escape through really tiny holes. Once the pressure is equal inside and out, there is two-way travel of gases through the holes and the balloon stays the same size. If you can keep your balloons cool, the gas molecules have less energy to help them escape!

This amazing cocoon belongs to a type of moth called Urodidae that lives mostly in wet climates, such as the Amazon rainforest. The caterpillar weaves the basket-like cocoon and then pupates inside. The open mesh design allows rain to pass through and helps to prevent fungi from growing. The cocoon hangs from a leaf on a long thread of silk, keeping the pupa safe from rainforest ants. There is an opening at the bottom, through which the newly emerged moth will climb out.
