Superfamily VESPOIDEA 1479 



Species Group Rufinodus 



The species of this group build the most complex nests in the family Eumenidae. The known 

 species construct a linear series of cells in old borings in twigs. Each cell is closed with a com- 

 plex plug consisting of a layer of macerated pith above which is a layer of mud or sand. At matu- 

 rity the larva moves through the pith layer into the earthen layer and moves the earthen parti- 

 cles around, spinning them together with silk to form a cocoon.
