Mark commented that this female Brimstone was so well camouflaged against the leaf she settled on at Alners Gorse when he visited the reserve on 29/07/19.
Not so were the caterpillars of the Marsh Fritillary butterfly which is found at Alners Gorse,. The mite, trombidium breei seen on one of the caterpillars is often found on butterflies and other insects but apparently does them no harm.
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.
