Eragenia is a genus of mud-nesting spider wasps in the family Pompilidae, formerly included in the genus Priocnemella . The genus has some 16 described species, with only one species in North America, Eragenia tabascoensis , restricted to southern Texas. [1]

Description

Wasps of the genus Eragenia are small, thin, and wiry. These wasps look almost identical to those of the genus Ageniella , though they are separated by two things: Eragenia has a "trough-like impression on the lateroapical margin of the clypeus", and a "curved, spine-like bristle on the apex of the anterior tibia". Eragenia tabascoensis is tawny (red, can be yellow) in color, with yellow wings. The wings are banded in black. [1]

Habitat

This genus lives in open areas, and at the edges of forests. It can live in forests as well, hunting in sunny patches. Adults are not found at flowers. [1]

Nests

Eragenia congrua , found in Brazil, uses Corrinid spiders to provision the nests, which are bored in soft wood. [1]

<span class="mw-page-title-main">Tarantula hawk</span> Common name for two genera of wasps

A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas. Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it to a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living host. They are found on all continents other than Europe and Antarctica.

<span class="mw-page-title-main">Spider wasp</span> Family of wasps

Wasps in the family Pompilidae are commonly called spider wasps, spider-hunting wasps, or pompilid wasps. The family is cosmopolitan, with some 5,000 species in six subfamilies. Nearly all species are solitary, and most capture and paralyze prey, though members of the subfamily Ceropalinae are kleptoparasites of other pompilids, or ectoparasitoids of living spiders.

Vespoidea is a superfamily of wasps in the order Hymenoptera. Vespoidea includes wasps with a large variety of lifestyles including eusocial, social, and solitary habits, predators, scavengers, parasitoids, and some herbivores.

<span class="mw-page-title-main">Mud dauber</span> Common name for several species of wasp

Mud dauber is a name commonly applied to a number of wasps from either the family Sphecidae or Crabronidae which build their nests from mud; this excludes members of the family Vespidae, which are instead referred to as "potter wasps". Mud daubers belong to different families and are variable in appearance. Most are long, slender wasps about 1 inch (25 mm) in length. The name refers to the nests that are made by the female wasps, which consist of mud molded into place by the wasp's mandibles. Mud daubers are not normally aggressive, but can become belligerent when threatened. Stings are uncommon.

<i>Caladenia</i> Genus of orchids

Caladenia, commonly known as spider orchids, is a genus of 350 species of plants in the orchid family, Orchidaceae. Spider orchids are terrestrial herbs with a single hairy leaf and a hairy stem. The labellum is fringed or toothed in most species and there are small projections called calli on the labellum. The flowers have adaptations to attract particular species of insects for pollination. The genus is divided into three groups on the basis of flower shape, broadly, spider orchids, zebra orchids and cowslip orchids, although other common names are often used. Although they occur in other countries, most are Australian and 136 species occur in Western Australia, making it the most species-rich orchid genus in that state.

<i>Ophrys insectifera</i> Species of flowering plant in the orchid family Orchidaceae

Ophrys insectifera, the fly orchid, is a species of orchid and the type species of the genus Ophrys. It is remarkable as an example of the use of sexually deceptive pollination and floral mimicry, as well as a highly selective and highly evolved plant–pollinator relationship.

<i>Cheiracanthium punctorium</i> Yellow sack spider

Cheiracanthium punctorium, one of several species commonly known as the yellow sac spider, is a spider found from central Europe to Central Asia. They reach a length of about 15 mm, and their bite can penetrate human skin; the bite has been compared to a wasp sting, perhaps a bit more severe, although susceptible persons can have stronger reactions, like nausea. Females build an egg sac of about 4 cm in high grass. It opens below and is aggressively defended.

The rose robin is a small passerine bird native to Australia. Like many brightly coloured robins of the Petroicidae, it is sexually dimorphic. The male has a distinctive pink breast. Its upperparts are dark grey with white frons, and its tail black with white tips. The underparts and shoulder are white. The female is an undistinguished grey-brown. The robin has a small black bill and eyes.

The white-starred robin is a species of bird in the Old World flycatcher and chat family Muscicapidae. It is also sometimes more simply called the starred robin. It is monotypic within the genus Pogonocichla. There are around twelve subspecies. The species is found in East and southern Africa. It is a forest species, occurring in montane forest in the north of its range but closer to sea level further south. This is a brightly coloured robin with a bright yellow breast and belly, a slate coloured head with spots on the eyes and throat and blueish wings.

<span class="mw-page-title-main">Wasp</span> Group of insects

A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder. The wasps do not constitute a clade, a complete natural group with a single ancestor, as bees and ants are deeply nested within the wasps, having evolved from wasp ancestors. Wasps that are members of the clade Aculeata can sting their prey.

<i>Sceliphron laetum</i> Genus of wasps

Sceliphron laetum is a wasp in the family Sphecidae, the mud-dauber wasps. Like other members of this genus, it is a solitary species and builds cells out of mud in which to rear its young, provisioning them with paralysed spiders, and laying an egg in each. This wasp is native to Australia and southeastern Asia.
