At first glance, this insect looks like a wasp, but it's actually a fly! This is Mydas clavatus, the clubbed Mydas fly.

Mydas flies are a comparatively small family; there are 471 described species worldwide. They're generally large in size, and the family even contains the largest fly known to man: Gauromydas heros, a South American species with a four-inch wingspan!

Despite their size and intimidating appearance, Mydas flies are perfectly harmless. While this species has evolved to resemble a spider wasp -- and will even jab its abdomen in an imitation of stinging -- it doesn't have a stinger, and it also can't bite. The larvae of these flies feed on beetle larvae, while the adults only feed on pollen and flower nectar. If you spot one in your garden, have no fear!

Thanks to VMNH Associate Curator of Invertebrate Zoology Dr. Kal Ivanov for the identification! #BenInNature
