Here’s a picture from springtime in Devon to light up these wintry days – a brimstone butterfly on a dandelion flower.

It’s a fairly shaggy individual with weak markings bleached out by strong sunshine, probably over-wintered. The distinctive green colouring suggests it’s probably a male.

Feeding from the dandelion.

At first I thought it was a clouded yellow, but the markings and time of year suggest brimstone.
