Description Studies conducted on sphecid fauna of Bangalore revealed a total of 38 species in 22 genera. They represented three families of the division Spheciformes (superfamily Apoidea): Ampulicidae, Sphecidae and Crabronidae. Ampulicidae was represented by the subfamily Ampulicinae with a single genus Ampulex Jurine and species Ampulex compressa (Fabricius), while Sphecidae was represented by three subfamilies, Sceliphrinae (2 genera; 4 species); Sphecinae (2 genera and 6 species) and Ammophilinae (1 genus and 3 species). Crabronidae was represented by highest number of species, genera and subfamilies. Of the 38 species of sphecid wasps collected, 25 of 11 genera were crabronids. They represented five subfamilies: Astatinae (Dryudella 2 species), Bembicinae (Bembix 3 species; Bemicinus 2 species and Hoplosoides 1 species); Crabroninae (Larra 3 species; Liris 2 species; Trypoxylon 2 species; Oxybelus 2 species; Crabro, Tachysphex, Tachytes, and Pison 1 species each); Philanthinae (Cerceris and Philanthus 1 species each), and Pemphredoninae (Carinostigmus 1 species). Of the 38 species collected, 29 were new records to Bangalore, including four species – Hoplisoides impiger, Larra carbonaria, Philanthus basalis and Sphex splendidus, recorded for the first time from India. A Checklist of sphecid wasps of Bangalore has been prepared. Studies on sphecid diversity in different ecological habitats revealed undisturbed land to be most diverse (13 species; H‟ = 2.48) and disturbed land with least number of species (4; H‟ = 1.33).
Observations recorded on the nesting habits of Chalybion bengalense revealed that the wasp used existing cavities like unused electrical sockets for nesting and provisioned cells with spiders. A wasp spent on an average 5.92 per cent of its time searching for nesting site, 10.35 per cent of time for cleaning and preparing the nest, 58.80 per cent of time for hunting and provisioning and 20.71 per cent time for nest closure. The number of spiders provisioned per cell ranged from 8 to 28. Seven families of spiders were brought and the most frequently taken prey belonged to the family Thomisidae (29.4%).
