This was taken in Cambridge Botanical gardens on 16/6/08.


It looks rather like Eupeodes luniger (again) but I was wondering if it was something different this time as the markings look a bit different and there's a dark mark on the tip of the head that's not there on other pictures I've got of that species. I also noticed that the abdomen seemed particularly thin and wide, don't know if that's significant.

Thanks

Will

Stubbs refers to a 'species C', close to luniger, that has a broadly bilobed black area on the frons a bit like the one in your photo. Just a thought.
