Larval/Pupal mud chambers constructed on twig - Eumenes
Near Edgewood County Park, San Mateo County, California, USA June 2, 2015
Two of the three pupae are visible in my palm, the third is still in the cavity of the chamber here. The longer pupa is approximately 6mm (using a 10mm size for the chamber, based on comparison to my thumbnail in the 1st photo of the series...which is 15 mm long).
