Hi, I notice that Jackharr has posted an excellent Chalkhill Blue photo taken in Cambridgeshire in this months competition. Jack reckons ab. caerumaculae, but could it also be a Gynandromorph?
I also noticed that ab. caerumaculae in the Cockayne database was found at Royston, so perhaps this aberation is mainly found in that area?

Looked like a halved Gynandromorph to me too!

Looks like a Gynandromorph to me too. The abdomen is slightly longer at one side. You can tell by the size of the both sides of the body usually.
