Aphaenogaster picea
Pitch-black Collared Ant
Aphaenogaster picea is a species of ant in the family Formicidae. It is known for its gut microbiome composition, which has been studied in relation to worker task behaviors and refuse pile interactions. The species is found at higher elevations in the eastern United States, particularly in Virginia, where it has been documented at 900–1000 meters above sea level. Workers exhibit task specialization without morphological subcastes, including nurse, forager, and refuse pile interaction roles.
Callophrys irus arsace
Callophrys irus arsace is a historically reported subspecies of the frosted elfin butterfly, originally described from coastal regions of the southeastern United States (Carolinas and Virginia). Genetic analysis of preserved specimens found no evidence that this subspecies is genetically distinct from the nominate subspecies C. i. irus. Field surveys conducted in 2019 and 2021 failed to locate any extant populations within its historical range. The subspecies has not been observed in over two decades and may be extirpated.
Cuterebra buccata
rabbit bot fly
Cuterebra buccata is a New World bot fly in the family Oestridae, commonly known as the rabbit bot fly. Adults are large, bumble bee-sized flies that lack functional mouthparts and do not feed. The species is host-specific to lagomorphs, particularly cottontail rabbits (Sylvilagus floridanus). Larvae develop subcutaneously in warbles, feeding on host fluids rather than tissue. Adults are rarely encountered in the field and have short lifespans focused on reproduction.

Cymindis elegans is a ground beetle species in the genus Cymindis, first described by LeConte in 1846. It belongs to the subfamily Lebiinae and tribe Lebiini within the family Carabidae. The species is known from Virginia in the United States. Very little specific information about its biology, ecology, or behavior has been documented.
Dalmosella tenuis
Dalmosella tenuis is a species of rove beetle in the family Staphylinidae, subfamily Pselaphinae. It is a small beetle belonging to the tribe Trichonychini within the diverse Pselaphinae, a group known for their compact bodies and reduced elytra. The species was described by Thomas L. Casey in 1897 and occurs across eastern North America.

Dalopius virginicus is a species of click beetle in the family Elateridae. The genus Dalopius belongs to the subfamily Dendrometrinae, a group of click beetles characterized by their ability to produce a clicking sound through a prosternal process that fits into a mesosternal cavity. Very little published information exists specifically for this species. The species epithet "virginicus" suggests a potential association with the state of Virginia or the broader Virginian biogeographic region in eastern North America, though this has not been confirmed in the available literature.
Decusa expansa
Decusa expansa is a rove beetle species in the family Staphylinidae, subfamily Aleocharinae, described by John Lawrence LeConte in 1866. It belongs to the tribe Oxypodini within the subtribe Dinardina. The species has been documented from several eastern and midwestern U.S. states. Like other aleocharine rove beetles, it is likely small-bodied with reduced elytra typical of the family.
Euhadenoecus fragilis
Tawney's Cave Cricket, tawneys cave cricket
Euhadenoecus fragilis is a species of camel cricket in the family Rhaphidophoridae. It was described by Hubbell in 1978. The species is known from cave environments in North America, with documented occurrences in Virginia. Like other members of the family Rhaphidophoridae, it is wingless and adapted to subterranean habitats.
Gammarus pseudolimnaeus
Northern Spring Amphipod
Gammarus pseudolimnaeus is a freshwater amphipod crustacean inhabiting lotic (flowing water) environments in North America. The species exhibits complex behavioral ecology, including size-selective predation vulnerability to fish predators such as brook trout and sculpins, and chemically-mediated responses to predation risk that influence reproductive behavior. Population dynamics are characterized by univoltine (single annual) generation cycles with high mortality during early life stages and winter periods. The species serves as an important prey item in stream food webs and has been extensively studied as a model organism for freshwater invertebrate ecology, toxicology, and predator-prey interactions.

devil crayfish, devil crawfish
Lacunicambarus diogenes, commonly known as the devil crayfish or devil crawfish, is a primary burrowing crayfish native to eastern North America. This species constructs and inhabits burrows in wet, muddy terrestrial habitats rather than living in permanent surface water. Its burrowing activities create refugia used by numerous other species, including documented use by eastern cicada killer wasps (Sphecius speciosus) as brooding habitat. The species ranges across the Atlantic Coastal Plain and Piedmont ecoregion from New Jersey to Georgia, with disjunct populations in Louisiana.

virginiensis
Notopygus virginiensis is a species of ichneumonid wasp described by Cushman in 1915. It belongs to the family Ichneumonidae, one of the largest families of parasitoid wasps. The genus Notopygus is part of the diverse ichneumonoid complex, with species typically characterized by specialized parasitoid life histories targeting other insects. Very little specific biological information has been published for this particular species.
Pseudanophthalmus hoffmani
Hoffman's Cave Beetle
Pseudanophthalmus hoffmani, known as Hoffman's cave beetle, is a species of ground beetle in the family Carabidae. It is endemic to Virginia, United States. The species belongs to a genus of troglobitic beetles specialized for subterranean environments.
Pseudanophthalmus holsingeri
Holsinger's Cave Beetle
Pseudanophthalmus holsingeri, known as Holsinger's Cave Beetle, is a troglobitic ground beetle endemic to Virginia, United States. The species was described by Thomas C. Barr in 1965. As a member of the genus Pseudanophthalmus, it is adapted to subterranean cave environments.
Pseudopolydesmus collinus
Rolling Hills Flat-back
Pseudopolydesmus collinus is a flat-backed millipede in the family Polydesmidae, described by Hoffman in 1974. It belongs to the order Polydesmida, characterized by their dorsoventrally flattened bodies. The species is known from limited records in Virginia, United States. As with other members of its genus, it likely inhabits moist forest floor environments typical of polydesmid millipedes.
Pseudopolydesmus paludicolus
Pseudopolydesmus paludicolus is a species of flat-backed millipede in the family Polydesmidae, described by Hoffman in 1950. It belongs to a genus characterized by a flattened body form typical of polydesmidan millipedes. The species epithet 'paludicolus' (from Latin 'palus' meaning marsh and 'cola' meaning dweller) suggests association with wetland or marshy habitats. Documentation of this species remains limited, with few published records beyond original description.
Scaphinotus incompletus
incomplete snail-eating beetle
Scaphinotus incompletus is a species of ground beetle in the family Carabidae, commonly known as the incomplete snail-eating beetle. It is one of the "snail-eating beetles" in the genus Scaphinotus, characterized by adaptations for predation on terrestrial mollusks. Adults are brachypterous (short-winged), a trait common in this genus that reflects their ground-dwelling lifestyle and reduced need for flight. The species is known from a restricted range in the Appalachian region of the eastern United States.
Trichosirocalus
rosette weevils, crown weevils
A genus of small true weevils native to the Palearctic region. Several species have been widely introduced to North America, Australia, and New Zealand as biological control agents for invasive thistles. The genus was historically treated as containing a single species, T. horridus, but integrative taxonomic studies using molecular and morphological data have revealed multiple distinct species with different host associations.
