Bandara johnsoni
Bandara johnsoni is a species of leafhopper in the family Cicadellidae, order Hemiptera. The species was originally described as Eutettix johnsoni by Van Duzee in 1894. It belongs to the genus Bandara, a group of true bugs commonly known as leafhoppers.

Bembidion acticola
Bembidion acticola is a species of ground beetle in the family Carabidae. It is known from a narrow geographic range along the Atlantic coast of the eastern United States. The species was described by Casey in 1884. Very little ecological or behavioral information has been published for this species.

Boreus reductus
Snow scorpionfly
Boreus reductus is a wingless species of snow scorpionfly in the family Boreidae, order Mecoptera. Adults are active during winter months and can be observed hopping across snow and ice. Unlike many Mecoptera, this species lacks functional wings entirely. Adults and larvae feed on mosses and liverworts. Males possess enlarged, upward-curving genitalia that resemble a scorpion's stinger, giving the group its common name. The species engages in a distinctive mating behavior where males carry females on their backs.

Caecidotea kenki
Caecidotea kenki is a spring-dwelling asellid isopod found in the eastern United States. Originally described as Asellus kenki by Bowman in 1967, it is one of only three asellid species in Maryland habitually associated with springs rather than subterranean caves. It is distinguished from the six obligate cave-dwelling Caecidotea species in the region by its surface water habitat preference.

Cambarus dubius
Upland Burrowing Crayfish
Cambarus dubius, commonly known as the Upland Burrowing Crayfish, is a burrowing crayfish species native to the central and southern Appalachian region of the eastern United States. The species has a complex taxonomic history with multiple distinct color phases historically recognized across different geographic areas. Recent taxonomic work has restricted C. dubius sensu stricto to populations with orange dorsal and lateral coloration and cream ventral surfaces, found in the central and northern Allegheny Mountains and high elevations of the Appalachian Plateau. The species constructs distinctive burrow systems and faces conservation concerns due to limited distribution data and habitat alterations.

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.

Euphydryas phaeton
Baltimore Checkerspot
Euphydryas phaeton, commonly known as the Baltimore Checkerspot, is a North American butterfly in the family Nymphalidae. It has been the official state insect of Maryland since 1973. The species is part of the checkerspot group within the genus Euphydryas, which includes several closely related species with similar wing patterns and ecological requirements.

Lacunicambarus diogenes
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.

Marietta timberlakei
Marietta timberlakei is a species of parasitic wasp in the family Aphelinidae, described by Hayat in 1986. The species is named in honor of the American entomologist Philip H. Timberlake, who made extensive contributions to the study of Hymenoptera, particularly bees and wasps. As a member of the genus Marietta, it is likely a hyperparasitoid, a trait common to other species in this genus. The species has been recorded from Hawaii and Maryland in the United States, as well as Brazil.

Toumeyella liriodendri
tuliptree scale
Toumeyella liriodendri, the tuliptree scale, is a soft scale insect (Coccidae) native to North America and specialized on Liriodendron tulipifera (tuliptree or yellow-poplar). This univoltine species overwinters as second-instar nymphs on twigs, matures to adults in spring, and produces eggs that hatch into crawlers in early summer. First-instar nymphs feed on leaf undersides before migrating back to twigs in autumn. Males are unknown; reproduction is presumed parthenogenetic. Heavy infestations cause branch dieback, reduced growth, and honeydew production that supports sooty mold growth. The species has been the subject of recent genomic research, with a 536Mb genome assembly revealing it as an early-diverging soft scale with 17 chromosomes.

Trichonephila clavata
Jorō spider, Joro Spider, Parachute spider
Trichonephila clavata, commonly known as the Jorō spider, is a large orb-weaving spider native to East Asia that has become established as an invasive species in the southeastern United States since approximately 2010. First confirmed in Georgia in 2014, it has expanded rapidly across multiple states through a combination of ballooning dispersal and human-mediated transport. The species is notable for its substantial size, striking coloration, and extensive golden webs, but poses minimal risk to humans due to small fangs and docile behavior. Its physiological adaptations—including higher metabolic rate, faster heart rate, and greater cold tolerance than its congener Trichonephila clavipes—suggest potential for continued northward range expansion.
