Old nest and cocoons - Trypoxylon politum
Copyright © 2009 Beatriz Moisset

Old nest and cocoons - Trypoxylon politum
Peace Valley Nature Center, Bucks County, Pennsylvania, USA
October 21, 2009
At the bottom or far end of each coccoon there was a black, dry, ring-shaped pellet of what I guess is frass (meconium?).
The pellets are similar to the ones I found on these tube nesters
