Agenioideus birkmanni
Agenioideus birkmanni is a spider wasp in the family Pompilidae, first described by Banks in 1910. As a member of the genus Agenioideus, it belongs to a group of small to medium-sized wasps that paralyze spiders to provision nests for their larvae. The species is part of a Nearctic genus with approximately 15 recognized species, most of which are poorly known biologically. No specific behavioral or ecological observations have been documented for this particular species.

Ammosphex anomalus
Ammosphex anomalus is a species of spider wasp in the family Pompilidae, originally described by Dreisbach in 1950 as Pompilus anomalus anomalus. The species was later transferred to the genus Ammosphex. It is part of the aculeate wasp group within Hymenoptera. Very limited biological information is available for this species, with only a single observation recorded in iNaturalist and minimal published literature. The genus Ammosphex contains species that are generally associated with hunting spiders as prey for their larvae, consistent with the biology of Pompilidae.

Bethylidae
Flat wasps
Bethylidae is a family of aculeate wasps in the superfamily Chrysidoidea, commonly known as flat wasps due to their dorsoventrally compressed body form. The family exhibits a biology intermediate between parasitoid and predatory wasps: females sting and paralyze prey (primarily beetle and lepidopteran larvae), then oviposit on the immobilized hosts. Most species are small (2–10 mm), with females often wingless or apterous while males are always winged. The family contains eight recognized subfamilies and approximately 96 genera, with highest diversity in tropical and subtropical regions.

Chrysidoidea
Cuckoo Wasps and Allies
Chrysidoidea is a large, cosmopolitan superfamily of aculeate wasps comprising approximately 6,000 described species across seven extant families. The group includes three large, common families—Bethylidae, Chrysididae (cuckoo wasps), and Dryinidae—and four small, rare families—Embolemidae, Plumariidae, Sclerogibbidae, and Scolebythidae. All members are parasitoids or cleptoparasites of other insects. The superfamily is traditionally considered the basal taxon within Aculeata, with some species capable of stinging though their venom is harmless to humans. Members of Dryinidae and Embolemidae exhibit a unique life cycle where larvae begin development inside the host body and later form an external sac (thylacium) protruding from the host abdomen.

Colpa octomaculata texensis
Colpa octomaculata texensis is a subspecies of mammoth wasp in the family Scoliidae, first described by Saussure in 1858. It belongs to a group of large-bodied parasitoid wasps whose larvae develop on scarabaeid beetle grubs. Recent phylogenetic research using ultraconserved element (UCE) data has clarified the evolutionary position of the genus Colpa, finding it to be sister to the tribe Scoliini and rendering the traditional tribe Campsomerini non-monophyletic. This subspecies represents part of a taxonomic complex that has historically been poorly resolved due to limited systematic study.

Cryptocheilus attenuatum
Cryptocheilus attenuatum is a species of spider wasp in the family Pompilidae, described by Banks in 1933. Like other members of its genus, it is a solitary wasp that hunts spiders to provision nests for its larvae. The species has been documented visiting flowers for nectar, particularly at blooming saltcedar (Tamarix) trees in Colorado. Observations suggest males may establish territories around nectar sources to encounter females.

Dielis tolteca
Toltec scoliid wasp
Dielis tolteca is a species of scoliid wasp native to western North America and Mesoamerica. The species is known to parasitize scarab beetle grubs, with females hunting underground hosts to provision their offspring. Adults have been observed feeding on flowering plants, particularly mustards (Brassicaceae) and goldenrods (Solidago). The species has been documented in McInnis Canyons National Conservation Area in western Colorado, where it is active as a spring-emerging species.

Dracunesia
Dracunesia is a genus of small parasitoid wasps in the family Bethylidae, described in 2018 by Alencar and Azevedo. The genus was established based on specimens from Brazil, representing a distinct lineage within this family of aculeate wasps. Bethylidae are known as flat wasps, characterized by their laterally compressed bodies and parasitoid lifestyle, primarily attacking immature stages of various insects. As a recently described genus, knowledge of Dracunesia remains limited to the original taxonomic description.

Entypus aratus
Entypus aratus is a species of spider wasp in the family Pompilidae, described by Townes in 1957. Members of this genus are solitary wasps that hunt spiders as prey for their larvae. The species is known from a small number of observations, suggesting it may be uncommon or underrecorded.

Esagonatopus niger
Esagonatopus niger is a species of dryinid wasp in the family Dryinidae, an aculeate hymenopteran group. Dryinidae are parasitoid wasps known for their distinctive morphology, including chelate (pincer-like) forelegs in females used to capture hosts. The genus Esagonatopus belongs to this family of solitary wasps that develop as parasitoids of Hemiptera, particularly leafhoppers and planthoppers. The species epithet 'niger' refers to its black coloration.

Evagetes mohave
Evagetes mohave is a species of spider wasp in the family Pompilidae, described by Nathan Banks in 1933. The genus Evagetes is characterized by a blocky, robust thorax that distinguishes it from the related genus Aporus, which has a more streamlined thorax that slopes gradually toward the head. Members of the genus Evagetes share with Aporus relatively short and thick antennae. The species epithet 'mohave' suggests an association with the Mojave Desert region of southwestern North America.

Myrmosula nasuta
Myrmosula nasuta is a species of myrmosid wasp in the family Myrmosidae, a small group of parasitoid wasps within the aculeate Hymenoptera. Members of this family are poorly known and rarely encountered, with limited biological data available. The genus Myrmosula contains species characterized by distinctive morphological features, though specific details for M. nasuta remain sparse in published literature.

Rhopalum atlanticum
Rhopalum atlanticum is a species of solitary wasp in the family Crabronidae, described by R. Bohart in 1974. The genus Rhopalum comprises small, predatory wasps known as sand wasps that provision nests with paralyzed prey. This species occurs in North America and Middle America. Like other members of its genus, it likely excavates burrows in sandy soils and hunts small insects to provision larval cells.

Sapygidae
Club-horned Wasps
Sapygidae is a small family of solitary kleptoparasitic aculeate wasps containing approximately 80 described species. They are generally black wasps with white or yellow markings, superficially resembling some Tiphiidae or Thynnidae. Females oviposit into the nests of solitary bees, where their larvae consume both the host larvae and the food stores provisioned for them. The family has limited economic importance, though some host species are important pollinators. Fossil sapygids are known from mid-Cretaceous Burmese amber and Upper Eocene Baltic amber.

Sierolomorphidae
Sierolomorphidae is a small family of aculeate wasps containing 13 extant species across two genera, Sierolomorpha and Proscleroderma. The family has a fossil record extending to the Early Cretaceous, with specimens known from amber deposits. They are solitary wasps of rare occurrence, predominantly distributed in the Northern Hemisphere.

Tachypompilus ferrugineus annexus
Tachypompilus ferrugineus annexus is a subspecies of spider wasp in the family Pompilidae. It belongs to a group of large, solitary wasps that hunt spiders to provision nests for their larvae. The species Tachypompilus ferrugineus is known for its distinctive rusty or reddish coloration. This subspecies was described by Nathan Banks in 1944.

A spider wasp subspecies in the family Pompilidae. Members of the genus Tachypompilus are solitary, ground-nesting wasps that provision their nests with paralyzed spiders as food for their larvae. This subspecies was described by Banks in 1919.
