Wasps of the genus Sphex are cosmopolitan predators that sting and paralyze prey insects. Sphex is one of many genera in the old digger wasp family Sphecidae, though most apart from the Sphecinae have now been moved to the family Crabronidae. There are over 130 known Sphex species.
Sceliphron, also known as black mud daubers or black mud-dauber wasps, is a genus of Hymenoptera of the Sphecidae family of wasps. They are solitary mud daubers and build nests made of mud. Nests are frequently constructed in shaded niches, often just inside of windows or vent openings, and it may take a female only a day to construct a cell requiring dozens of trips carrying mud. Females will add new cells one by one to the nest after each cell is provisioned. They provision these nests with spiders, such as crab spiders, orb-weaver spiders and jumping spiders in particular, as food for the developing larvae. Each mud cell contains one egg and is provided with several prey items. Females of some species lay a modest average of 15 eggs over their whole lifespan. Various parasites attack these nests, including several species of cuckoo wasps, primarily by sneaking into the nest while the resident mud dauber is out foraging.
Pemphredonidae is a family of aphid wasps formerly treated as the subfamily Pemphredoninae. There are 19 genera and 556 described species in the family.
Ammophila is the type genus of the subfamily Ammophilinae of the hunting wasp family Sphecidae. Ammophila is a large and cosmopolitan genus, with over 200 species, mostly occurring in the warmer regions of all continents apart from Antarctica.
Cryptocheilus is a genus of spider wasps of the subfamily Pepsinae, found in the world's warmer regions. They vary in size from medium to large and are often strikingly coloured. The females construct multicellular nests in cavities, once built each cell is stocked with a spider, captured by the female. They are found in open habitats such as heaths, meadows and forest edges.
Pimpla are a worldwide genus of the parasitic wasp family Ichneumonidae.
Chlorion is a genus of parasitoid wasps in the family Sphecidae. Species have been recorded from the Americas, Africa and tropical Asia through to Java; they appear to prey mostly on Orthopteran insects.
Scolia is a genus of scoliid wasps in the subfamily Scoliinae. There are over 200 described species in Scolia.
Crossocerus is a genus of square-headed wasps in the family Crabronidae. There are at least 250 described species in Crossocerus.
Crabro is a genus of square-headed wasps belonging to the family Crabronidae. There are at least 80 described species in Crabro, found in the Nearctic and Palaearctic (Holarctic).
Nysson is a Holarctic genus of kleptoparasitic wasps in the family Crabronidae. Over 100 species are known.
Oxybelus is a genus of wasps in the family Crabronidae. The species are found worldwide except in the Australasian realm. They are especially represented in the Palearctic. Oxybelus is the largest genus in Crabronidae, with 264 species known. Oxybelus wasps sometimes gravitate towards people, flying around travellers and landing on them, even when they are shooed away. It is not known why they do it, however it might possibly be them trying to drink sweat for its minerals.
Trypoxylon is a genus of wasps in the family Crabronidae. All Trypoxylon species that have been studied so far are active hunters of spiders, which they paralyse with a venomous sting, to provide as food to their developing larvae. Depending on the species, they will either construct their own nest from mud or find cavities that already exist. These cavities can range from keyholes to nail holes to previously abandoned nests, and are generally sealed with mud to create cells for their larvae.
Ectemnius ruficornis is a species of square-headed wasp in the family Crabronidae.
Ectemnius continuus is a species of square-headed wasp in the family Crabronidae. It is found in Africa, Europe and Northern Asia, North America, and Southern Asia.
Larrini is a tribe of square-headed wasps in the family Crabronidae. About 15 genera and more than 1,300 described species are placed in the Larrini.
