Subject: Daniel – What’s This Fly?

I thought I’d discovered all of the flies that could possibly come to our little patch, but here’s another. Can you please help? It spent a lot of time on catnip blooms and the adjacent native geranium (I think I have it properly distinguished from geranium.) It is very shy and moves fast, but came back over and over again.

We believe we have correctly identified your Bee Fly as Dipalta serpentina based on this BugGuide image. According to BugGuide: “Larvae are parasitoids of pupae, and perhaps also larvae, of antlions (Myrmeleontidae)” and “In Calif. species is most abundant in August and September” which makes your sighting right on schedule.
Thanks! We just love sighting “new to us” creatures in the back.
