Proctacanthus rufus

Proctacanthus rufus is about the same size of P. milbertii and P. hinei but it is not as common as these two species throughout central and southern Wisconsin. I have only seen this species at three sites, one on Wisconsin Point in Douglas County, a single individual on the Eau Claire River north of Fall Creek, and a single individual at the Petenwell Dam area in Juneau County. Like with P. milbertii, I was following the female around as she was feeding on her prey of Bombus sp. and a male mated with her in flight and all three were flying around as a unit making lots of noise.
