A Review of Nesting Behavior in theGenusEntomognathus, With Notes onE. MemorialisBanks (Hymenoptera: Sphecidae)

[摘要] The genusEntomognathuscontains at least 4o species, half inthe Ethiopian and in the Palaearctic, Nearctic, Oriental, and Neotropicalregions (Leclercq, 1954, 1955, 1961, 1963; Nouvel andRibaut, 1956; Krombein, 1963). Relatively little is known aboutthe nesting behaviors, host preferences, or life histories of membersof this genus. Only the PalaearcticE. (Entomognathus) brevisvander Linden has been studied in any detail, and almost nothing isknown about the four U. S. species belonging to the subgenusToncahuaOne of the purposes of the present paper is, therefore,to amalgamate information on the host preferences, nesting behaviors,life histories, and immature stages of the species ofEntomognathus,based upon a review of the world literature. The major portion ofthis paper details the components of the nesting behavior ofE. (Toncahua)memorialisBanks, describes the mature larva and cocoon,and compares this species and related crabronine and larrine waspsin nesting ethology and larval and cocoon morphology. The adultwasps and prey beetles have been placed in the S. U. N. Y. Collegeof Forestry Insect Museum. and the mature larva has been depositedin the Museum of Comparative Zoology, Harvard University.
