The warm spell in mid-February was a great tonic to us all, with the first signs of spring accompanying it. Crucially, for me, it coincided with the first appearance of my beloved butterflies from hibernation. Four species of butterfly hibernate during the winter as an adult: Brimstone, Peacock, Small Tortoiseshell and Comma. Red Admiral also overwinters as an adult but does not enter a dormant state and can be seen on sunny days throughout the winter. Of all the butterflies, it is the Brimstone which is synonymous with early spring. Keen butterfly observers note the date of their first Brimstone sighting and this year on the Island, it coincided with Valentine’s Day.

The male Brimstone matches the colour of sulphur perfectly and emerges from its slumbers dashing off in search of females. However, the paler female emerges later so its early pursuit is in vain. They can survive until the end of May, having the longest adult stage of the UK’s butterflies. Brimstone is among the oldest butterfly names, being established in the 17th century. Because of its colour, there is even the suggestion that the Brimstone was the original butterfly but this has yet to be proven.
Brimstone can be seen anywhere although the early records come predominantly from woodlands. Firestone Copse and Parkhurst Forest are two sites where you are likely to see one. If there is a cold spell in March, Brimstone will return to its wintering quarters and hibernate until the warm weather returns.
With butterflies starting to appear, now is a good time to register with Butterfly Conservation’s Garden Butterfly Survey. If you do not have a garden, you can still take part at an allotment or community space. You can survey your site throughout the year recording the species you see and enter your sightings online. You can find out how to take part at www. gardenbutterflysurvey.org
Recording butterflies is so important. The recent State of the UK’s Butterflies 2022 report has just been published and revealed the alarming news that 80% of butterflies in the UK have declined since the 1970s.
Don’t forget to record the butterflies you see out on your walks. There is an excellent iRecord free app which you can download to your phone. Enjoy your butterflies and let me know what you have seen.
