| Brimstone Butterfly | Orange-tip Butterfly |
The sulphur-yellow butterfly that heralds spring — males are an unmistakable lemon-yellow, females a paler greenish-white; one of the longest-lived British butterflies, spending the winter as an adult hibernating among ivy and evergreen leaves, then emerging on warm February days to become the first butterfly many people see each year.
A delicate white butterfly of spring hedgerows — males have vivid orange wingtips that give the species its name, while females are white with black tips, easily mistaken for other whites; the underside of both sexes is marbled green and white, providing perfect camouflage on cow parsley flowers where they roost.
