Butterflies - Brimstone (Gonepteryx rhamni)

The Brimstone is common sight in Warwickshire, Coventry and Solihull.

Warm sunny days in early March brings the Brimstone out from hibernation. The Brimstone is one of the longest living of British Butterflies and is the only species outside the Nymphalidae family to hibernate as an adult butterfly.

The bright, rich yellow of the male Brimstone butterfly cannot be confused with any other UK butterfly. The female however, is a very pale yellow/white and is easily confused for a Large White.

The Brimstone is thought to be the original 'butter-coloured fly'.
