About: A fairly large pale yellow butterfly, with a wingspan of about 7cm. Adults hibernate, and may be seen flying on warm days throughout the year, although they are most common in the spring. Usually seen in ones or twos, never very common although widespread. They can be found in damp woodlands, along sunny woodland rides, mature hedgerows and in large gardens. The foodplants are Buckthorn and Alder Buckthorn, two shrubs of wet woodland.
How to identify: A large, pale yellow butterfly with a greyish body and single orangey spots in the middle of each wing. The wings have a characteristic shape, with pointed wing tips.
Where: Across most of England and Wales.
Fantastic fact: The Brimstone is the original 'butter fly', named for the colour of its wings
