The male Brimstone butterfly is yellow; the female is pale green. It's easily recognised by the unique shape of the wings.
This butterfly always rests with the wings together.

Brimstone butterflies hibernate over the Winter. Look out for them on the wing in March when they are searching for a mate. I find that they don't usually stop in my garden during the Spring but can be seen flying by.
The best chance of seeing Brimstone butterflies in my garden is in August. Usually I will find one on a Buddleia at some time in August.
Enjoyed watching a male Large White butterfy taking an interest in a female Brimstone butterfly on 4 September 2003. He chased her around the back garden until he finally gave up.
