The great golden digger wasp returns!

The great golden digger wasps (Sphex ichneumoneus), which I wrote about in a post last year on free will and the Concorde fallacy, returned this year to the same spot in front of Higley Hall at Kenyon College in the soft, gravelly soils under an overhang. A swarm of dedicated females has been entertaining our equally dedicated summer science students and visitors. The nest site is conveniently right outside large floor-to-ceiling windows, perfect for viewing the activity of this wasp species. Their short lives will come to an end soon, but they have been able to dig, provision, and complete dozens of burrows. Brava, wasps. I hope this site remains popular for the species for years to come.
