08.10.2022 Our friend the Robber Fly

They seem to be mean little guys.  They eat other insects including flies.  But, aside from being part of the balance Nature supports, they also keep pests under control.

The deer fly can spread a stomach virus to animals and occasionally to humans so  E. aestuans is doing us a big favor.  Besides the virus deer flies have a nasty little bite.

    I’m all for a few less deer flies! Nice catch, for both you and the robber fly. 😉

    I’ve had the dubious pleasure of meeting the deer fly, and those critters are mean. The robber fly is welcome to as many as it can catch.

    So the robber fly is doing a great job and protects nature on his own way.

    Sounds like it does an important job! We don’t get deer flies here but we can get horseflies and they have a mean bite!

    Hmmm… just yesterday I was photographing a large insect that appeared to be some sort of fly but I had no clue what and still haven’t done any research, but I wonder if it might be one of these. Will have to compare photos. I agree, it certainly does look like a mean little guy.
