Snakeflies are a group of predatory insects comprising the order Raphidioptera with two extant families: Raphidiidae and Inocelliidae, consisting of roughly 260 species. In the past, the group had a much wider distribution than it does now; snakeflies are found in temperate regions worldwide but are absent from the tropics and the Southern Hemisphere. Recognisable representatives of the group first appeared during the Early Jurassic. They are a relict group, having reached their apex of diversity during the Cretaceous before undergoing substantial decline.
The genus Halictus is a large assemblage of bee species in the family Halictidae. The genus is divided into 15 subgenera, some of dubious monophyly, containing over 200 species, primarily in the Northern Hemisphere. Most species are black or dark brown, sometimes metallic greenish-tinted, with apical whitish abdominal bands on the terga.
Melitta is a genus of bees in the family Melittidae. It includes about 40 species restricted to Africa and the northern temperate zone. Most of the species are Palaearctic, though three rare species occur in North America.
The Berothidae are a family of winged insects of the order Neuroptera. They are known commonly as the beaded lacewings. The family was first named by Anton Handlirsch in 1906. The family consists of 24 genera and 110 living species distributed discontinuously worldwide, mostly in tropical and subtropical regions. Numerous extinct species have also been described. Their ecology is poorly known, but in the species where larval stages have been documented, the larvae are predators of termites.
Thyreus is an Old World genus of bees, one of many that are commonly known as cuckoo bees, and are cleptoparasites of other species of bees, mostly in the genus Amegilla. They all have strongly contrasting patterns of coloration - three species from the Sydney region, Thyreus nitidulus, T. lugubris, and T. caeruleopunctatus are bright blue and black.
Hilara is a genus of dance flies, in the fly family Empididae.
Panurgus is a genus of mining bees belonging to the family Andrenidae, subfamily Panurginae.
Xylocopa aestuans, or Xylocopa (Koptortosoma) aestuans, is a species of carpenter bee. It is widely distributed in Southeast Asia.
Sphecodes is a genus of cuckoo bees from the family Halictidae, the majority of which are black and red in colour and are colloquially known as blood bees. Sphecodes bees are kleptoparasitic on other bees, especially bees in the genera Lasioglossum, Halictus and Andrena. The adults consume nectar, but because they use other bees' provisions to feed their offspring they do not collect pollen.
Anthidiellum is a genus of rotund resin bees in the family Megachilidae. There are more than 60 described species in Anthidiellum.
Ammobatini is a tribe of cuckoo bees in the family Apidae. There are about 8 genera and more than 130 described species in Ammobatini.
Panurginus is a genus of bees in the family Andrenidae. There are more than 50 described species in Panurginus.
Ammobates is a genus of cuckoo bees belonging to the family Apidae.
Flavomeliturgula is a genus of bees belonging to the family Andrenidae.
Stenosmia is a genus of bees belonging to the family Megachilidae.
Parammobatodes is a genus of cuckoo bees belonging to the family Apidae.
Camptopoeum is a genus of bees of the subfamily Panurginae.
