Atrusca aggregata
Atrusca aggregata is a species of cynipid gall wasp described by Weld in 1926. Like other members of the family Cynipidae, this tiny wasp induces the formation of characteristic galls on oak leaves. The genus Atrusca is known for producing colorful, detachable leaf galls on various Quercus species. Adult females emerge from galls and use their ovipositor to inject eggs into leaf tissues, initiating the next generation of galls.
Atrusca capronae
striped oak-apple gall wasp
Atrusca capronae, commonly called the striped oak-apple gall wasp, is a cynipid wasp species that induces characteristic galls on oak leaves in southwestern North America. The species is most frequently observed in Arizona but occurs throughout the region where its host plants grow. The wasp's common name derives from the striped appearance of the galls it produces, though stripe intensity varies geographically. The species is considered fairly common within its range.
Atrusca cubitalis
Atrusca cubitalis is a species of cynipid gall wasp, a group of tiny wasps known for inducing characteristic plant galls on their host plants. As a member of the family Cynipidae, this species exemplifies the highly specialized host relationships typical of gall wasps, where each species typically induces a distinct gall type on a specific host plant or closely related group of plants. The genus Atrusca is known for producing colorful and structurally distinctive galls on oak leaves (Quercus spp.), with A. cubitalis specifically associated with post oak (Quercus stellata) based on related species observations. The life cycle involves the female wasp using her ovipositor to inject eggs into leaf tissue, after which the developing larvae secrete plant growth hormones that cause the formation of a specialized gall structure within which they feed and develop.
Atrusca unica
Atrusca unica is a species of cynipid gall wasp in the family Cynipidae. Like other gall wasps, it induces the formation of specialized plant structures called galls on its host plant. The genus Atrusca is known for producing colorful, prominent leaf galls on oaks (Quercus spp.). This species appears to be relatively well-documented with 227 observations on iNaturalist, suggesting it is not exceptionally rare, though specific details about its biology remain limited in the provided sources.
Aulacidae
Aulacid Wasps
Aulacidae is a small, cosmopolitan family of parasitoid wasps in the superfamily Evanioidea, containing approximately 200 known species across two extant genera: Aulacus and Pristaulacus. These wasps are primarily endoparasitoids of wood-boring insects, specifically targeting larvae of wood wasps (Xiphydriidae) and xylophagous beetles in the families Cerambycidae and Buprestidae. They are closely related to Gasteruptiidae and Evaniidae, sharing the distinctive evanioid trait of having the metasoma attached high on the propodeum above the hind coxae. Despite their wide distribution, aulacids are rarely collected and poorly studied, particularly in the Southern Hemisphere.
Aulacus brevicaudus
Aulacus brevicaudus is a species of parasitoid wasp in the family Aulacidae, a group often overlooked due to their resemblance to ichneumon wasps. The genus Aulacus comprises generally smaller species compared to the related genus Pristaulacus. Like other aulacids, this species is associated with wood-boring beetle hosts. Aulacidae as a family contains two genera and approximately 185 species globally, with 32 species recorded in North America.
