The Mutillidae, velvet ants, are hairy wasps that usually show significant dimorphism with females being wingless and having the sclerites of the mesosoma fused whereas males are mostly winged with articulated mesosomal plates. Larvae develop as parasites in the nests of other stinging wasps… Continue reading Mutillidae


Belongs within: Pompiloidea.Contains: Ceropales, Ctenocerinae, Pompilinae, Leptodialepis, Calopompilus, Hemipepsis, Pepsini, Psoropempula, Ageniellini, Priocnemis, Dipogon. The Pompilidae, spider hawks, are a cosmopolitan group of wasps that develop as predators or parasites of spiders. They can typically be distinguished from other aculeate wasps by a distinct groove dividing the mesopleuron into two sections. Characters (from Shimizu 1994):… Continue reading Pompilidae


Belongs within: Euaculeata.Contains: Amblyoponinae, Proceratiinae, Ponerinae, Dorylinae, Cerapachys, Ectatommini, Myrmicinae, Formicinae, Myrmeciinae, Pseudomyrmecinae, Dolichoderinae. The Formicidae are the ants, a diverse and familiar clade of social wasps with a caste division between wingless workers and winged reproductives, with the female reproductives (the ‘queens’) shedding their wings after mating. An elongate scape (first antennal segment) is… Continue reading Formicidae


Belongs within: Larrini. Liris is a diverse, cosmopolitan genus of mostly black, ground-nesting wasps that usually take crickets of the family Gryllidae as prey. Prey is lightly paralysed before being transported to the nest which is often a pre-existing cavity (Bohart & Menke 1976). Characters (from Bohart & Menke 1976): Upper inner angle of eye… Continue reading Liris

Larropsis: letting your prey do the work for you Published 12 June 2024 Keen-eyed wanderers in sandier regions of North America may observe wasps of the family Crabronidae going about their business, visiting flowers and hunting prey with which to stock their nests. Among the members of this family unique to this… Continue reading Larropsis


Belongs within: Megachilini. Hackeriapis is an Australasian genus of relatively small resin bees, most of which (excepting some larger species) have strong transverse grooves on the second and third metasomal tergites (Michener 1965). Resinous confusion Published 12 February 2024 Australia (like most other parts of the world) is home to a wide diversity of solitary… Continue reading Hackeriapis


Belongs within: Euaculeata.Contains: Agriomyia, Zeleboria, Lophocheilus, Aeolothynnus, Thynnus. The Thynninae are a group of wasps exhibiting extreme sexual dimorphism. Males are winged and have the apex of the hypopygium produced and often spinose; females are wingless and often lack functional ocelli. Males often have the hypopygium produced and spinose or dentate (Kimsey 2004). <==Thynninae |… Continue reading Thynninae

Belongs within: Anthophila.Contains: Halictinae, Nomia, Lipotriches. The Halictidae are a family of short-tongued bees distinguished by a strongly arcuate basal vein in the fore wing (Engel 2001). The Halictidae: short tongues and waxy chambers Published 25 April 2020 In an earlier post, I introduced you to the diverse group of bees known as the Halictinae.… Continue reading Halictidae


Belongs within: Apoidea.Contains: Megachilidae, Apidae, Andrenidae, Halictidae, Stenotritidae, Colletidae, Melittinae. The Anthophila, bees, are a diverse and well-marked clade of herbivorous wasps, characterised primarily by the presence of at least some plumose hairs on the body (though these may be few in some groups). Particularly dense patches of these plumose hairs may form a scopa… Continue reading Anthophila
