It is a night flier that is sometimes attracted to light. During the day, it finds a secluded place to await the return of darkness. At first glance the coppery color and dark wings suggest a wasp. Not only does it look like a wasp, the attitude of the wings makes it appear to be an agitated wasp.
The presence of halteres, those short rods
capped with white knobs, quickly identifies it as a type of fly. Halteres are situated behind the wings and function as
stabilizers to allow balanced flight.
All flies have them.
This is another false image. That is the top of the head, not a
mouth. The protrusions are antennae.
This is not my first encounter
with this species, but it is the first time I’ve found a live specimen. A fly on the hoof is much more interesting
than a desiccated corpse.
fly deposits its egg directly on the beetle.
When the egg hatches, the larva burrows inside and begins feeding. The beetle eventually dies and the fly larva pupates
inside the dead beetle’s body. I’ll have
to start cracking open dead June Beetles to see if I can find a fly pupa.
