Family AMPULICIDAE 



These primitive sphecoid wasps occur principally in the tropics of the Old and New Worlds. 

 Appropriately, they prey upon cockroaches, one of the most primitive of insect orders. The biolo- 

 gy of only a few species has been observed. The nests are constructed in pre-existing cavities or 

 crevices, such as in twigs, beneath bark of trees or in the soil. Unlike other sphecoids, the prey is 

 carried backwards on foot as in most pompilid wasps.
