Laphria ithypyga

This species has been recorded from Wisconsin, however I still haven’t located the original article that documents this. In the 1965 catalog of North American Diptera, Martin and Wilcox list this species as occurring in PA and MD. A list of the Wisconsin Asilidae located in the collection at UW-Madison includes this species.

Identifying characteristics

Abdomen with segments three through six with golden yellow hairs, hairs on the posterior of the thorax form a narrow triangle that extends at least to the middle of the thorax. The dorsal surface of the sixth abdominal segment has a single projections in the center of the rear of this segment on the male.

Similar species

There are several species that may be mistaken for this species. L. index is the species that most commonly is confused with this species farther south. They superficially look very much alike, but there are differences in the genitalia in both the male and the female, and in the male, the 6th abdominal segment has two distinct projections at the posterior end rather than the single projection in this species. This species could also be confused with L. scorpio, a northern species that is very similar but the narrow fringe of hair from the posterior of the thorax never reaches the middle.




June through August


Not a common species in Wisconsin. Look for it in far southern Wisconsin.
