Superfamily SPHECOIDEA 1677 



Prey: Syritta pipiens (L.), Chrysogaster sp., Toxomerus occidentalis Curr., 

 Sphaeroplwria contigua Macq., Mesogmpta marginata (Say), Parapenium sp., Paragus 

 tibialis (Fall.); Syrphidae seem to be the preferred prey, but occasionally Anthomyiidae 

 are used in Europe.

In Europe cephalotes (Oliv.) has been reported to nest in both sound lumber and in decaying 

 trunks. 



cephalotes (Olivier). Ont, Que., Conn., N. Y., N. J., Pa., Md., III.; Europe. Ecology: In Europe 

 nests both in sound lumber and in decaying logs; several females use a common 

 entrance but presumably have their own cells. Probably adventive in N. Amer. Prey: In 

 Europe stores many species of muscoid Diptera, occasionally Tabanidae and Syrphidae, 

 and one specimen of Nematinae was found in a cell.
