ciliata
Sympistis ciliata is a species of moth in the family Noctuidae, first described by Smith in 1900. It belongs to the large and diverse genus Sympistis within the subfamily Noctuinae. The species is documented from North America, though specific details regarding its biology, ecology, and distribution remain limited in published sources.
Theridion michelbacheri
Theridion michelbacheri is a species of cobweb spider in the family Theridiidae, first described by Levi in 1957. It is known from the United States, with records indicating presence in North America. As a member of the genus Theridion, it shares the general characteristics of this large and diverse group of comb-footed spiders, though specific details about its biology remain poorly documented.
Toxonprucha killamae
Toxonprucha killamae is a moth species described by James T. Troubridge in 2020. It belongs to the genus Toxonprucha within the subfamily Erebinae of the family Erebidae. The species was recently described, and published information remains limited. It is part of the diverse assemblage of underwing and related moths in the Noctuoidea superfamily.
Trimitomerus riversii
Trimitomerus riversii is a species of dead-log beetle in the family Pythidae, first described by Horn in 1888. It is endemic to North America. The genus Trimitomerus comprises elongate beetles associated with decaying wood habitats. Like other Pythidae, this species is thought to develop in rotting wood, though specific natural history details remain poorly documented. The family Pythidae is a small group of beetles historically allied with Bostrichidae and Anobiidae, now recognized as a distinct lineage within Bostrichiformia.
Uleiota truncata
Uleiota truncata is a small beetle species in the family Silvanidae, first described by Motschulsky in 1845. Members of this family are commonly known as silvanid flat bark beetles, typically associated with decaying wood and bark habitats. The genus Uleiota contains multiple species distributed across various regions, though detailed species-level biology for U. truncata remains poorly documented in accessible literature.
Walckenaeria palustris
Walckenaeria palustris is a species of dwarf spider in the family Linyphiidae, described by Millidge in 1983. The specific epithet 'palustris' (Latin for 'of the marsh') suggests association with wetland or marshy habitats. Like other members of the genus Walckenaeria, it is a small-bodied spider with characteristic genitalic structures used for species identification. The species has been recorded in Canada based on available distribution data.
Zanclognatha atrilineella
Black-lined Fan-foot
Zanclognatha atrilineella is a small litter moth in the family Erebidae, described by Augustus Radcliffe Grote in 1873. It is commonly known as the Black-lined Fan-foot. The species is restricted to the southeastern United States. Adults have a wingspan of approximately 23 mm.
