The garden has been awash with insect life recently, including lots of ladybirds. This pair was getting fruity. You can just see the abdomen curving down to meet the other, at the bottom left. Are they actually the same species though, I wondered, given they look completely different?

I used this UK Safari page and this handy allotment society guide to help me identify them as most likely both Harlequins. They can display a large variation in colouration but always have brown legs, which is most obvious in the top one here. If I had a top-down photo I'd be able to see if there is an M/W shape on the top of the head, which would also help identify them positively as Harlequins.
