Apennines, Prov. Piacenza, N Italy. 06 July 2020. Short sequence showing a Chrysis species of Ruby-tailed Wasp (Chrysididae) backing into a hole selected for a sleeping place. It went in head first to start so it could check out conditions, then Came out and backed in. Up to four wasps, of at least two chrysidid species, would appear on the same debris-covered boulder every late afternoon during about 10 days observation. Sometimes two would share the same hole.
