Nesting habits of potter and mason wasps

(I am trying to make some sense of the variety of nests in the subfamily Eumeninae. So I hope that putting some images together might help.)

Wasps of the subfamily Eumeninae (potter and mason wasps) construct a variety of nests. The ones we are most familiar with are the little pots, but there are other varieties. Some use preexistent holes such as hollow twigs; others build a cell different from the typical pot. It may be possible to identify the species or at least the genus by the nests, so I tried to group the different kinds of nests that we have in the guide.

Potters: Eumenes, several species make pots, usually you find them singly, but sometimes they seem to be in clusters or in a row. Zeta nests seem very similar.


1 and 2: Eumenes bollii 3: Eumenes crucifera


1, 2, 3: Eumenes fraternus 4: an unusual pot also identified as Eumenes fraternus

A few variations on groupings of nests made by unidentified Eumenes

Eumenes spp.

The pots built by Zeta argillaceum are very similar to those of Eumenes some are aligned in a row.
Zeta argillaceum

Hole nesters:
Ancistrocerus antilope

Ancistrocerus gazella

Ancistrocerus spilopterus

Euodynerus sp.

Euodynerus crypticus

Euodynerus hidalgo

Euodynerus megaera

Euodynerus pratensis

Monobia quadridens

Parazumia symmorpha

Pterocheilus

Neither pot nor hole nesters. There seems to be some construction on an open surface.
Ancistrocerus catskill

Ancistrocerus waldenii

Pachodynerus erynnis

Pachodynerus guadulpensis

Very nice, Beatriz!
Thanks for putting this overview/summary together...great idea, and well done. Very informative & helpful.
