Dog Day Harvest Fly

A member of the cicada family, dog day harvest flies abound in Spruce Woods Park and are evident by their aerial buzzing as they fly from tree to tree. The sound is actually the mating call of male dog day harvest flies trying to attract females. The fly is about an inch long with a wing span of three inches and has distinctive green markings on its black body. Hear their call on my short video.
