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.
Allonemobius fasciatus
striped ground cricket
Allonemobius fasciatus, the striped ground cricket, is a small ground-dwelling cricket native to North America. It is a model organism in evolutionary biology, particularly for studies of hybridization with its sister species A. socius, reproductive isolation, and life history adaptation. The species exhibits complex diapause strategies including bet-hedging, where females produce offspring with variable developmental phenotypes to spread risk across unpredictable environmental conditions. Populations show altitudinal adaptation in life cycle timing, with photoperiodic regulation of development compensating for shorter growing seasons at higher elevations.
Allonemobius griseus
Gray Ground Cricket
Allonemobius griseus, commonly known as the Gray Ground Cricket, is a small cricket species in the family Trigonidiidae. Originally described as Nemobius griseus by Walker in 1904, it was later transferred to the genus Allonemobius. The species is documented from multiple U.S. states and Canadian provinces, with iNaturalist observations indicating established populations in the field. Like other ground crickets, it is likely associated with ground-level vegetation and leaf litter habitats.
Allonemobius sparsalus
Allonemobius sparsalus is a small cricket species described by Fulton in 1930, currently treated as a synonym within the genus Allonemobius (family Trigonidiidae). The species has been recorded from coastal and southeastern United States localities. Like other members of Allonemobius, it belongs to a group of ground-dwelling crickets often associated with moist or grassy habitats. The taxonomic status of this name requires verification against current revisions of the genus.
Allonemobius tinnulus
Tinkling Ground Cricket
Allonemobius tinnulus, commonly known as the tinkling ground cricket, is a small cricket species in the family Trigonidiidae. It is native to eastern North America and produces a distinctive high-pitched, tinkling song. The species was originally described as a subspecies of Nemobius fasciatus before being elevated to full species status. It inhabits forest floor environments and leaf litter.
Eunemobius carolinus
Carolina Ground Cricket
Eunemobius carolinus, the Carolina ground cricket, is a small orthopteran in the family Trigonidiidae. It is widely distributed across North America, with records from Alabama, Arizona, Arkansas, California, Colorado, and other states. The species was first described by Scudder in 1877 and includes three recognized subspecies. It inhabits ground-level environments typical of ground crickets.
Eunemobius melodius
Melodious Ground Cricket
Eunemobius melodius is a small ground cricket native to eastern North America. It produces a distinctive, melodious trill that distinguishes it acoustically from congeners. The species inhabits moist ground-level vegetation and leaf litter in forested and semi-open habitats. It is one of several Eunemobius species whose identification relies heavily on male calling song characteristics.
Nemobius
wood cricket, ground cricket
Nemobius is a genus of small crickets in the family Trigonidiidae, commonly called wood crickets or ground crickets. The genus serves as the type genus for the subfamily Nemobiinae. Nemobius species are notable hosts for horsehair worms (Paragordius), which manipulate cricket behavior to facilitate their own reproduction. The genus contains approximately eight described species distributed across Europe and other regions.
Neonemobius
Small Ground Crickets
Neonemobius is a genus of small ground crickets in the family Trigonidiidae, subfamily Nemobiinae. The genus was established by Hebard in 1913 and contains six recognized species, all native to North America. Members are small-bodied crickets typically found in ground-level habitats.
Neonemobius cubensis
Cuban Ground Cricket
Neonemobius cubensis is a small ground cricket known from the Caribbean region and parts of the southeastern United States. The species is notable for an unusual mating behavior in which females feed on glandular tibial spurs of males during copulation, leaving visible damage on previously mated males. It belongs to the family Trigonidiidae, a group of crickets often associated with ground-dwelling habits.
Neonemobius eurynotus
California ground cricket, Bay Area ground cricket
Neonemobius eurynotus is a small ground cricket endemic to coastal California. It occurs primarily in the San Francisco Bay Area, where it inhabits terrestrial ground-level environments. The species was described in 1918 and remains poorly studied, with limited observational records available.
Neonemobius mormonius
Collared Ground Cricket, Mormon Ground Cricket
Neonemobius mormonius, commonly called the collared ground cricket or Mormon ground cricket, is a small ground cricket species in the family Trigonidiidae. It inhabits arid and semi-arid regions of southwestern North America. The species is relatively well-documented with over 1,500 observations on iNaturalist.
Neonemobius near-mormonius
Neonemobius near-mormonius is a small ground cricket in the family Trigonidiidae, characterized by its diminutive size and cryptic coloration. The species is part of a genus of tiny crickets commonly known as "ground crickets" or "pygmy crickets" that inhabit leaf litter and ground-level vegetation. Like other members of Neonemobius, it produces high-frequency calling songs that are often inaudible to unaided human hearing. The specific epithet "near-mormonius" suggests morphological similarity to N. mormonius, a closely related species with which it may be confused.
Neonemobius palustris
Sphagnum Ground Cricket, Marsh Ground Cricket
Neonemobius palustris is a small ground cricket in the family Trigonidiidae, found in eastern North America. Males measure approximately 5.7 mm and females about 6.8 mm in length. The species is strongly associated with moist habitats, particularly dense patches of sphagnum moss, sandhill seeps, and wet longleaf pine savannas. It produces a distinctive calling song consisting of trills several seconds in duration separated by pauses of similar length.
Neonemobius variegatus
Variegated Ground Cricket, Smaller Spotted Ground Cricket
Neonemobius variegatus is a species of ground cricket in the family Trigonidiidae, commonly known as the variegated ground cricket or smaller spotted ground cricket. The species is native to North America and has been documented in several eastern and midwestern U.S. states. Like other members of the genus, it occupies ground-dwelling habitats and is part of the diverse cricket fauna of the region. The specific epithet "variegatus" refers to its patterned or varied coloration.
