This was one of the first robber flies that I learned when I took a photo of the one that captured a Little Wood-Satyr. This is a fairly distinctive robber fly, long and slender, especially the female with the long pointed abdomen.
This is mainly a brownish robber fly with very light yellowish brown legs, somewhat darker wings, and a very long, thin abdomen.
None in Wisconsin.
mid-June through mid-July.
Not very common, but widespread in central Wisconsin. I have only seen two in one day twice.
