Your letter to the bugman:  Hello-
We spotted this bug on the deck railing today. Can you enlighten us as to what it is? We are near Flathead Lake & some stagnant ponds. We’ve never seen anything like it. Thanks!

Robber Fly: Stenopogon inquinatus

Thank you so much! I read up on the Stenopogon & found that it can be a predator of hummingbirds. This one was hanging out on the railing, right by the hummingbird feeder. Next time we see it, we’ll definitely shoo it away.
I really appreciate your fast response! Cheers!
Suzanne
