Good to know
Six things about the brimstone
Name The first butter-fly? One popular theory says the word "butterfly" comes from this butter-yellow species.
Disguise Hiding as a leaf The wings are shaped and veined like a leaf. Hibernating in ivy or holly, a brimstone is almost impossible to spot.
Life A long life Adults can live for around a year, which makes them one of Britain's longest-lived butterflies.
Resting Wings always closed A brimstone never opens its wings when it rests, which helps the leaf disguise.
Food Fussy caterpillars The caterpillars eat only buckthorn and alder buckthorn, so planting one helps them.
Colour Yellow or white The males are bright yellow. The females are a pale greenish-white and are often mistaken for a white butterfly.
The real thing
Photos of the brimstone
Out and about How to spot one Watch hedgerows and woodland edges on the first warm days of the year, often in February or March. With its wings closed it looks exactly like a pale green leaf.
Lend a hand How to help Plant buckthorn or alder buckthorn, the only shrubs its caterpillars eat. Thick ivy gives the adults a place to spend the winter.
