I have had this huge flying insect run me out of my flower beds for the past couple of years. I saw it attack a Digger Wasp in my vegetable garden last year! I am pretty sure it is a Mydas Fly, but I would like to know a little bit more information on it. What does it do? Does it sting? LOL
Hi again Monica,
This is a Mydas Fly, Mydas clavatus. The adults are predatory, feeding on caterpillars, other flies, bees and true bugs. I guess with your observation, we can add wasps to the menu. Also, your photo implies that they also feed on nectar which many flies do. Larvae live in rotting wood and probably feed on beetle larvae. Flies do not sting, but they will probably bite if mishandled.
