The Thynnidae (also known as thynnid wasps or flower wasps) are a family of large, solitary wasps whose larvae are almost universally parasitoids of various beetle larvae, especially those in the superfamily Scarabaeoidea. Until recently, the constituents of this family were classified in the family Tiphiidae, but multiple studies have independently confirmed that thynnids are a separate lineage. [1] [2] [3]


Most species are small, but they can be up to 30 mm long. The females of some subfamilies (all Diamminae, Methochinae, and Thynninae) are wingless, and hunt ground-dwelling (fossorial) beetle larvae, or (in one species) mole crickets. The prey is paralysed with the female's sting, and an egg is laid on it so the wasp larva has a ready supply of food. In species where both sexes are winged, males are similar in size to the females, but are much more slender. The males of species with wingless females, however, are often much larger than the females and have wings; the adults mate in the air, with the female carried by the male's genitalia. Adults feed on nectar, and are minor pollinators. As some of the ground-dwelling scarab species attacked by thynnids are pests, some of these wasps are considered beneficial as biological control agents. [ citation needed ]

<i>Sphex</i> Genus of wasps

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.

Tiger beetle Subfamily of beetles

Tiger beetles are a large group of beetles, from the Cicindelinae subfamily, known for their aggressive predatory habits and running speed. The fastest known species of tiger beetle, Cicindela hudsoni, can run at a speed of 9 km/h, or about 125 body lengths per second. As of 2005, about 2,600 species and subspecies were known, with the richest diversity in the Oriental (Indo-Malayan) region, followed by the Neotropics.

Scoliidae Family of wasps

The Scoliidae, the scoliid wasps, are a family of about 560 species found worldwide. They tend to be black, often marked with yellow or orange, and their wing tips are distinctively corrugated. Males are more slender and elongated than females, with significantly longer antennae, but the sexual dimorphism is not as apparent as in the Tiphiidae.

Vespoidea Superfamily of insects

Vespoidea is a superfamily of wasps in the order Hymenoptera, although older taxonomic schemes may vary in this categorization, particularly in whether to recognize the superfamilies Scolioidea or Formicoidea. Vespoidea includes wasps with a large variety of lifestyles: eusocial, social, and solitary habits, predators, scavengers, parasitoids, and some herbivores.

Gall wasp Superfamily of wasps

Gall wasps, also called gallflies, are a family (Cynipidae) in the wasp superfamily Cynipoidea within the suborder Apocrita of the order Hymenoptera. Their common name comes from the galls they induce on plants for larval development. About 1,300 species of this generally very small creature (1–8 mm) are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America.

Tiphiidae Family of insects

The Tiphiidae are a family of large, solitary wasps whose larvae are parasitoids of various beetle larvae, especially those in the superfamily Scarabaeoidea. Until recently, this family contained several additional subfamilies, but multiple studies have independently confirmed that these comprise a separate lineage, and are now classified in the family Thynnidae.

<i>Pison</i> Genus of wasps

Pison is a cosmopolitan genus of wasps within the family Crabronidae. The genus comprises 145 described species, although many species, especially in South America remain undescribed.

<i>Drakaea</i> Genus of orchids

Drakaea is a genus of 10 species in the plant family Orchidaceae commonly known as hammer orchids. All ten species only occur in the south-west of Western Australia. Hammer orchids are characterised by an insectoid labellum that is attached to a narrow, hinged stem, which holds it aloft. The stem can only hinge backwards, where the broadly winged column carries the pollen and stigma. Each species of hammer orchid is pollinated by a specific species of thynnid wasp. Thynnid wasps are unusual in that the female is flightless and mating occurs when the male carries a female away to a source of food. The labellum of the orchid resembles a female thynnid wasp in shape, colour and scent. Insect pollination involving sexual attraction is common in orchids but the interaction between the male thynnid wasp and the hammer orchid is unique in that it involves the insect trying to fly away with a part of the flower.

Pimplinae Subfamily of wasps

Pimplinae are a worldwide subfamily of the parasitic wasp family Ichneumonidae.

<i>Arthrochilus</i> Genus of flowering plants

Arthrochilus, commonly called elbow orchids, is a genus of about fifteen species of flowering plants from the orchid family (Orchidaceae) and is found in Australia and New Guinea. The flowers are pollinated by male thynnid wasps which attempt to mate with the flower and are held in place by hooks while the pollinium is transferred between insect and flower.

<i>Agenioideus</i> Genus of wasps

Agenioideus is a genus of spider wasps from the subfamily Pompilinae; the genus occurs in Europe, where 21 species are recorded, eastwards to Japan, in North America, South America, and Australia.

<i>Tenthredo</i> Genus of sawflies

Tenthredo is a genus of sawflies with more than 700 species of the family Tenthredinidae, subfamily Tenthredininae. It is of Holarctic distribution.

<i>Cyphononyx</i> Genus of wasps

Cyphononyx is a genus of spider hunting wasps in the family Pompilidae.

Brachycistidinae Subfamily of wasps

Brachycistidinae is a subfamily of the flower wasp family Tiphiidae that contains 10 genera and 85 species, and which is confined to the Nearctic zoogeographic region.

Tiphiinae Subfamily of wasps

Tiphiinae is one of the two subfamilies of the flower wasp family Tiphiidae, the other being the Nearctic Brachycistidinae. It is the larger of the two and has a worldwide distribution.

<i>Stizoides</i> Genus of wasps

<i>Hyptia</i> Genus of wasps
