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.

Caccoplectus is a genus of myrmecophilous (ant-loving) rove beetles in the family Staphylinidae, subfamily Pselaphinae. The genus was established by Sharp in 1887 and contains approximately nine described species. These beetles are associated with ant colonies, a common ecological strategy among pselaphine beetles. Most species have been described from the Neotropical region, particularly Central America.

Western Tiger Beetle
Cicindela oregona, commonly known as the Western Tiger Beetle, is a North American tiger beetle species found from the Rocky Mountains to the Pacific Coast and north into Alaska. It is closely related to C. duodecimguttata (Twelve-spotted Tiger Beetle), with which it forms a hybrid zone along the Front Range of the Rockies. The species exhibits distinctive microhabitat segregation with co-occurring tiger beetles, preferring moist stream edge habitats and showing physiological adaptations for foraging in wet conditions at temperatures between 25-38°C.
Cicindela willistoni echo
Echo Tiger Beetle
Cicindela willistoni echo is a subspecies of tiger beetle in the family Carabidae, commonly known as the Echo Tiger Beetle. It is found in saline habitats of the southwestern United States and northwestern Mexico. Larvae construct distinctive turreted burrows on barren saline flats, a feature shared with other subspecies of C. willistoni. The subspecies exhibits strong habitat fidelity for specific moisture and salinity conditions within salt flat environments.
Cicindela willistoni estancia
Torrance Tiger Beetle
Cicindela willistoni estancia is a subspecies of tiger beetle known from salt lake habitats in New Mexico. It was described by Rumpp in 1962 and is commonly called the Torrance Tiger Beetle. The subspecies shows a strong preference for the water's edge in salt flat environments, representing a distinct microhabitat specialization that reduces competition with sympatric tiger beetle species. Adult emergence is triggered by summer monsoonal rains, restricting activity to a relatively short post-monsoonal period.
Clypastraea ornata
minute hooded beetle, minute fungus beetle
Clypastraea ornata is a minute beetle in the family Corylophidae, commonly known as minute hooded beetles or minute fungus beetles. Adults measure approximately 2 millimeters in length. The genus Clypastraea is characterized by a pronotum with a shelf-like projection that conceals the head. This species is found in association with fungi and mold in rotting wood and under bark on dead trees. It is one of 61 species in ten genera of Corylophidae recorded north of Mexico.
Copestylum florida
Florida bromeliad fly
Copestylum florida is a syrphid fly species commonly known as the Florida bromeliad fly. It belongs to the genus Copestylum, a group of flies associated with bromeliad plants. The species has been documented in Florida and the Carolinas.
Hypochilus coylei
lampshade weaver
Hypochilus coylei is a lampshade spider described by Platnick in 1987 from the southern Appalachian Mountains of western North Carolina. It belongs to a relictual genus of microhabitat specialists with disjunct distributions across three North American montane regions. The species is sister to H. thorelli and exhibits extreme genetic divergence coupled with morphological stasis, characteristic of short-range endemic taxa with limited dispersal ability.
Hypochilus pococki
Pocock's lampshade-web spider
Hypochilus pococki is a relictual lampshade spider endemic to the southern Appalachian Mountains. It belongs to a paleoendemic genus distributed disjunctly across three montane regions in North America. The species exhibits extreme genetic divergence over small geographic distances, with five identified mitochondrial haplogroups, yet shows striking morphological stasis in male reproductive structures. As a microhabitat specialist, it has extremely low dispersal ability, leading to pronounced population genetic structuring.
Latridiidae
minute brown scavenger beetles, fungus beetles
Latridiidae is a cosmopolitan family of minute beetles containing approximately 1,050 described species in 29 genera, though true diversity is likely much higher. Adults range from 1.2 to 2 mm in length and are uniformly brown to black in coloration. The family is divided into two subfamilies: Latridiinae (glabrous, heavily sculptured dorsal surface, smooth pronotal margin) and Corticariinae (finely pubescent, lightly sculptured, serrate pronotal margin). Both adults and larvae are obligate mycetophages, feeding exclusively on fungal hyphae and spores.
Leptonetidae
cave spiders
Leptonetidae is a family of small, primitive haplogyne spiders first described by Eugène Simon in 1890. The family comprises approximately 22 genera and 400 species, though taxonomic boundaries have been revised recently with elevation of Archoleptonetinae to family rank (Archoleptonetidae). Leptonetids are characterized by their small size (2-5 mm), reduced eye number, and adaptation to dark, moist microhabitats. They represent a relict fauna with origins dating to the Cretaceous period and exhibit complex biogeographic patterns across the Holarctic.
Psyllipsocus decoratus
A small barklouse species in the family Psyllipsocidae, described by Mockford in 2011. Members of this genus are typically found in sheltered microhabitats and are characterized by reduced or absent wings. The species name "decoratus" suggests distinctive ornamental or patterned features.
Rhyopsocus
bird nest barklice
Rhyopsocus is a genus of barklice in the family Psoquillidae, commonly referred to as bird nest barklice. The genus contains more than 20 described species. These insects are associated with bird nests, where they feed on organic debris. They are small, soft-bodied insects typical of the order Psocodea.
Temnothorax texanus
Texas Acorn Ant
Temnothorax texanus is a species of acorn ant in the genus Temnothorax, described by Wheeler in 1903. The species is native to Texas and surrounding regions, where it inhabits small cavities such as hollow nuts, twigs, and other pre-existing shelters. Like other members of its genus, it is a small, cavity-nesting ant with a specialized lifestyle dependent on finding and occupying suitable microhabitats. The species has been documented in entomological collections and is recognized as part of the diverse North American Temnothorax fauna.
