Hayhurst’s Scallopwing

Staphylus hayhurstii

Hayhurst’s Scallopwing has only been seen in Grant County, in the far southwestern corner of the state. This species is widely distributed in the eastern U.S., but Wisconsin’s sighting is near the northernmost sighting of this species. This species is considered a rare stray in Wisconsin, but certainly could be expected along the Mississippi River counties.
