A white and a yellow butterfly on a bush

Shona was delighted to get this shot of a female Brimstone refusing to mate with the male, as it was her first ever shot of a stationery female Brimstone upperwing. Taken at Badbury Rings on 10/05/2019.

When a female butterfly has already mated, she will refuse further male advances: she needs to get on with laying her eggs, which she will do on the bush in the photograph, which is a buckthorn. She shows her refusal by having her wings open and raising up her abdomen, often with the genitalia extruded.
