Over the past couple of weeks (beginning mid-July) this guy has been seen flying around the yard and never let me approach closely enough for a photo. Until he became preoccupied… It becomes startled easily, but sits for long periods of time on the mulch in my garden, rarely landing on the plants. It’s about 1.5” long. It resembles some of the spider wasps or wood wasps, but I was a little overwhelmed trying to identify it myself. Thanks!
These mating Mydas Flies, Mydas clavatus, are excellent wasp mimics. You may read more about them on bugguide, where it is indicated: “Mating system in this species unknown. Different Mydas species apparently have different mating systems, including resource-defense polygyny and ‘hilltopping’.” BugGuide does have at least one image of a mating pair.
