At a nest site in Northern Italy of females of the weevil-hunting digger wasp Cerceris arenaria L. (Hymenoptera: Crabronidae) the provisioning activity and predator-prey relationship were investigated, in particular their specialization in choice of

Females of communal and eusocial Hymenoptera differ greatly in the treatment of conspecifics: communal species lack the nest membership-bias treatment via nestmate (NM) recognition, which is typical of eusocial Hymenoptera. Therefore, an analysis of

Cuckoo bees and velvet ants use different resources of their shared host bees, the former laying eggs on the host pollen stores and the latter on immature stages. We studied the activity patterns of the cuckoo bee Sphecodes monilicornis and the velve

Neotropical solitary bee‐hunting wasps of the genus Trachypus (Hymenoptera: Crabronidae) are ecologically and behaviourally little known. Here, we report information on prey types used by the digger wasp Trachypus denticollis Spinola in central Chi

Within the bee family Halictidae there have been three origins of sociality. Although detection of origins and reversal from sociality requires phylogenetic studies, at a behavioural level a predisposition to sociality can be detected by analysis of

In a study on the host association of the cuckoo wasp, Chrysis fulgida L., at two nesting sites in Northern Italy, it was observed emerging from nests of the mason wasp, Symmorphus crassicornis (Panzer). Although other species of eumenine wasps neste

The mature postdefecating larva of Trachypus denticollis Spinola is described. Larval morphology permits the separation of Trachypus Klug from Philanthus F., the two genera forming the subtribe Philanthina. The presence, in Trachypus, of maxillae wit

The contents of 21 trap-nests located in Sagarmatha National Park, Nepal, in 2002 and 2003 revealed interesting aspects of the biology of Ancistrocerus sikhimensis Bingham (Hymenoptera: Eumenidae). The nests included 2-7 brood cells separated by mud
