Location: Buena Vista Grassland
This was a robber fly trip to look for one of the rarest insects in WI. I haven't seen Promachus fitchii since 2008 and I have only seen it at this site. No one else has reported this species to me. Look for it in grassland areas. I saw 17 P. vertebratus and I did see one P. fitchii. Yeah!
