Many thanks for your reply. I don't have any with the wings open, but I have another that shows its body better:Its a little hard to tell. It could be a fly. Did you get any other shots with the wings out? Flies have two wings, wasps and bees (hymenoptera) have four.
Many thanks again. I did some googling using what you told me, and I think that this could be a great golden digger wasp:That looks like a hymenoptera. Flies don't (usually) have a petiole - the narrow stalk with abdomen at the end.
