Allonemobius
Robust Ground Crickets
Allonemobius is a genus of North American ground crickets in the family Trigonidiidae (subfamily Nemobiinae). The genus comprises at least 11 described species, including Allonemobius socius, A. fasciatus, and A. allardi. Members are notable for their sophisticated diapause strategies, with some species exhibiting embryonic diapause that allows survival across unfavorable seasons. Research on multiple species has revealed complex life history adaptations including bet-hedging strategies, altitudinal variation in voltinism, and physiological trade-offs between reproduction and immunity.

Alloxysta
Alloxysta is a genus of small parasitic wasps in the family Figitidae, subfamily Charipinae. The genus was described by Arnold Förster in 1869 and contains over 100 species with cosmopolitan distribution. Members are aphid hyperparasitoids, attacking primary parasitoids (aphidiid wasps) that develop within aphids. Some species exhibit thelytokous parthenogenesis induced by Wolbachia endosymbionts, where unmated females produce female offspring without mating.

Anurida
Anurida is a genus of springtails (Collembola) in the family Neanuridae, established in 1865 by Laboulbène. The genus has cosmopolitan distribution with species occupying diverse habitats including intertidal marine zones, river floodplains, riparian areas, and forest ecosystems. Well-studied species include the intertidal specialist Anurida maritima, which exhibits complex tidal-entrained behaviors, and the terrestrial A. granaria, which has documented mycophagous associations. The genus shows notable morphological diversity in chaetotaxy and eye reduction, with some species groups exhibiting cryptic genetic divergence despite morphological similarity.

Asobara
Asobara is a genus of parasitoid wasps in the family Braconidae containing approximately forty species. The genus is best known as parasitoids of Drosophila larvae, with Asobara tabida serving as a major model organism for studying parasitoid-host interactions and the hologenome concept. Members of this genus lack polydnaviruses, instead employing venom-based strategies to suppress host immune defenses. Several species, including A. tabida and A. japonica, exhibit obligate or facultative associations with Wolbachia endosymbionts that influence reproduction and host-finding behavior.

Blattidae
Household Cockroaches
Blattidae is a family of cockroaches in the order Blattodea, established by Latreille in 1810. The family includes several of the most common household and peri-domestic pest species, notably in the genera *Periplaneta*, *Blatta*, and *Eurycotis*. The family is distributed worldwide, with particular diversity in tropical and subtropical regions. Many species have adapted to human-altered environments, though numerous species remain restricted to natural habitats such as leaf litter and forest floors.

Bryobia
clover mites
Bryobia is a genus of spider mites in the family Tetranychidae, comprising over 130 described species with difficult taxonomy and many likely synonyms. These mites are among the largest spider mites, visible to the naked eye, and are distinguished by the arrangement of setae on their bodies. Most species reproduce asexually through thelytokous parthenogenesis, producing all-female populations. Several species are economically significant agricultural pests, including B. praetiosa (clover mite), B. rubrioculus (brown mite), and B. kissophila (ivy mite).

Chelymorpha
Argus tortoise beetles, tortoise beetles
Chelymorpha is a genus of tortoise beetles in the family Chrysomelidae, subfamily Cassidinae, containing more than 70 described species distributed primarily in the Americas. These beetles are characterized by their domed, tortoise-like body form with the elytra and prothorax forming a protective shield that can be drawn down to cover the head and appendages when disturbed. The genus exhibits extensive intraspecific color polymorphism, with some species showing remarkable variation in elytral coloration and maculation patterns. Chelymorpha species are predominantly associated with plants in the family Convolvulaceae, particularly morning glories (Ipomoea) and bindweeds (Convolvulus), though some species utilize other host plants. The genus has been extensively studied for its Wolbachia endosymbiont infections, color polymorphism maintenance, and larval defensive behaviors including cycloalexy.

Chorthippus
slant-faced grasshoppers
Chorthippus is a large genus of gomphocerine grasshoppers comprising approximately 230 described species, predominantly distributed in the Palaearctic realm. The genus was erected by Franz Fieber in 1852 and has been subdivided into subgenera including Altichorthippus, Chorthippus, and Glyptobothrus. Many species within this genus are morphologically cryptic and difficult to distinguish visually, particularly in mainland Eurasia where song patterns serve as the primary means of species identification. The genus contains notable species groups such as the Chorthippus biguttulus group, which includes the common field grasshopper.

Cnestus
ambrosia beetles
Cnestus is a genus of ambrosia beetles (Curculionidae: Scolytinae: Xyleborini) established by Sampson in 1911. Species in this genus are characterized by inbreeding reproduction through sib mating, cultivation of symbiotic ambrosia fungi as their sole nutritional source, and haplodiploid sex determination. The genus includes both native Asian species and invasive populations that have established in North America, Europe, and other regions. Cnestus mutilatus (camphor shot borer) is the most widely documented species, first reported in the United States in 1999 and subsequently detected in Europe. The genus exhibits complex evolutionary patterns, with some species containing cryptic sympatric lineages that are morphologically indistinguishable but genetically distinct.

Crioceris
asparagus beetle
Crioceris is a genus of leaf beetles (Chrysomelidae) commonly known as asparagus beetles. The genus includes both widespread agricultural pests and rare species restricted to specialized habitats. Several species are associated with Asparagus host plants, with C. asparagi and C. duodecimpunctata being notable invasive pests. Other species such as C. quinquepunctata and C. quatuordecimpunctata are rare and occupy steppe-like habitats in Eurasia. The genus has been subject to molecular barcoding studies to distinguish closely related species.

Cyphomyrmex
fungus-growing ants
Cyphomyrmex is a genus of small, drab-colored fungus-growing ants in the tribe Attini, found primarily in the Neotropics. These ants cultivate fungi in the tribe Leucocoprineae as their primary food source, with most species growing fungal nodules rather than full mycelial gardens. Colonies are typically monogynous and small, rarely exceeding 500 workers. The genus is divided into two species complexes: the strigatus complex (South America only) and the rimosus complex (southern North America to South America). Cyphomyrmex represents a basal lineage among attine ants and serves as sister group to Mycetophylax.

Delia radicum
cabbage root fly, cabbage maggot, spring cabbage fly, smaller cabbage fly
Delia radicum is a significant agricultural pest fly in the family Anthomyiidae, commonly known as the cabbage root fly or cabbage maggot. The larval stage causes damage by tunneling into roots and lower stems of cruciferous crops, while adults are small, grayish flies that emerge in spring. The species has a Holarctic distribution, occurring across Europe, North Africa, Asia, and North America. Research has documented complex interactions with microbial symbionts including Wolbachia and gut microbiota, which influence host fitness and plant-insect chemical ecology.

Diopsidae
Stalk-eyed Flies
Stalk-eyed flies are a family of true flies distinguished by their most conspicuous feature: eyes mounted at the ends of long lateral projections called eyestalks. This unique morphology is directly linked to their mating behavior, with males typically possessing longer eyestalks than females and using them in visual displays during courtship. The family occurs primarily in tropical and subtropical regions of Africa and Asia, with some species extending into the Arabian Peninsula and other areas. Several species are known agricultural pests, particularly as stem-borers in rice and other Poaceae.

Diplazon
Diplazon is a genus of parasitoid wasps in the family Ichneumonidae, subfamily Diplazontinae. The genus has cosmopolitan distribution with records from Europe, North America, and Asia. Species in this genus are known to parasitize syrphid fly larvae (hoverflies), with D. laetatorius being the most studied species. At least nine species occur in Japan alone, indicating substantial regional diversity.

Diplolepis
gall wasps, rose gall wasps
Diplolepis is a genus of gall-inducing wasps in the family Diplolepididae, most commonly associated with roses (Rosa spp.). These small wasps are notable for inducing complex, often conspicuous galls on their host plants through chemical manipulation of plant tissues. The genus includes both sexual and parthenogenetic species, with some like D. rosae reproducing primarily by thelytokous parthenogenesis. Diplolepis species exhibit intricate life cycles involving alternation between sexual and agamic generations, and their galls support diverse communities of parasitoids and inquilines.

Mossy Rose Gall Wasp, Rose Bedeguar Gall Wasp, Robin's Pincushion Gall Wasp
A gall-inducing wasp in the family Diplolepididae that forms distinctive mossy, pincushion-like galls on wild roses, primarily Rosa canina and Rosa arvensis. The species is notable for its predominantly parthenogenetic reproduction, with fewer than 5% males in most populations. Females lay up to 60 eggs in developing rose buds, inducing chemically-driven plant tissue distortion that creates the characteristic bedeguar gall. The wasp has been introduced to North America alongside cultivated roses.

Disholcaspis prehensa
clasping twig gall wasp
Disholcaspis prehensa is a gall-inducing cynipid wasp native to California that induces distinctive galls on scrub oak and leather oak. The species exhibits heterogony, alternating between sexual and asexual generations that produce two morphologically different gall types. The asexual generation forms conspicuous mushroom-shaped twig galls with clasping bases, while the sexual generation produces small, hidden bud galls.
