I learned something interesting with this picture. First, the parts I already knew. This fly was flitting around on some flowers, but then landed on this bracken fern. I noted that it looks a lot like a bumblebee. However, it has only two wings, not four- therefore, not a bee. It also doesn't fly like a bee. If an insect is sitting on a leaf like this, it's probably not a bee at all. It was definitely a fly- Order Diptera (two wings). After that, I was at the end of my knowledge and had to go hunting.
Flies that look like bees are robber flies. They are in the genus Laphria. But there are more genera which are all called robber flies in the family Asilidae. Worldwide, there are more than 7100 species of them. They are noted for having a long proboscis which they use to stab victims. They then inject a neurotoxin to kill the prey. The saliva also dissolves the internal organs of the victim, and the robber fly sucks this meal back through the proboscis. Yum.
To see another kind of robber fly, Ratty once posted a picture of a Giant Robber Fly
Most of these cousins have to get by with sharing the same common name. I think this one's formal name is Laphria thoracica
