A Note on the Mating Behavior of Empis gulosa Coquillett (Diptera: Empididae)

摘要

I present here the first description of the mating behavior of the empidid fly Empis gulosa. Males of this predatory species appear to provide their copulatory partners with a nuptial gift in the form of a small insect that the female consumes while mating. In northern Virginia, copulations occur in late April and early May primarily in the late afternoon or evening.
