One of the absolute joys of early spring is catching sight of a fluttering, lemon yellow butterfly. Amazingly the word ‘butter-fly’ is thought to have derived from "butter-coloured fly,” because of the yellowness of the male brimstone butterfly's wings!
The brimstone is a long lived butterfly, they live for up to a year after hatching into their adult form. After sleeping through the winter, the adults wake up and travel to find a mate, that’s why now is such a great time to spot them.
As well as their pale yellow colour, you can tell it’s a brimstone because of their distinctive leaf shaped wings.
