Smooth Cellophane-cuckoo Bee
Epeolus glabratus is a species of cuckoo bee in the family Apidae. As a cleptoparasite, females lay eggs in the nests of host bees rather than constructing their own nests or collecting pollen. The species is found in North America. Like other members of the genus Epeolus, it likely targets nests of polyester bees in the genus Colletes, though specific host associations for this species remain poorly documented.
Ephippiphora imitativa
Ephippiphora imitativa is a species of tortrix moth in the family Tortricidae. The specific epithet "imitativa" suggests a resemblance to other species. Based on the small number of iNaturalist observations (8), it appears to be rarely encountered or poorly known. As a member of Tortricidae, it likely possesses the characteristic bell-shaped resting posture and forewings that fold over the abdomen.
Ephuta pauxilla
Ephuta pauxilla is a species of velvet ant in the family Mutillidae. The genus Ephuta contains small to medium-sized mutillids found primarily in North America. Like all velvet ants, females are wingless and wasp-like in appearance, while males possess wings. The species is poorly documented with minimal published information available.
Epiblema coracinana
Epiblema coracinana is a small moth species in the leafroller family Tortricidae, subfamily Olethreutinae. Like other members of the genus Epiblema, it likely exhibits cryptic coloration adapted to its environment. The species is known from very few observations, with only two records documented on iNaturalist as of the source date.
Epitomus
Epitomus is a genus of ichneumon wasps in the family Ichneumonidae, established by Förster in 1869. The genus is poorly known, with only two observations recorded on iNaturalist and minimal published biological data. It has been documented from Denmark, Norway, and Sweden. As with other ichneumonid genera, members are presumed to be parasitoid wasps, but specific host associations and ecological details remain undocumented.
Eribolus longulus
Eribolus longulus is a species of frit fly in the family Chloropidae, first described by Loew in 1863. Like other members of this family, it is a small dipteran with reduced wing venation. The genus Eribolus contains species that are generally poorly studied, with limited published information on their biology and ecology.
Eriplatymetra lentifluata
Eriplatymetra lentifluata is a moth species in the family Geometridae, first described by Barnes and McDunnough in 1917. It belongs to the subfamily Ennominae, a diverse group of geometrid moths commonly known as inchworms or loopers due to their larval locomotion. The species is native to North America, though specific details about its biology and ecology remain poorly documented. Records of this species are sparse, with limited observational data available.
Eropterus arculus
Eropterus arculus is a net-winged beetle (family Lycidae) described by Green in 1951. The species is known from eastern Canada, with records from New Brunswick, Ontario, and Québec. Like other lycids, adults are characterized by soft, flexible elytra with distinct reticulate venation. The species is rarely encountered, with minimal published biological information available.
Eruga lineata
Eruga lineata is a species of ichneumon wasp in the family Ichneumonidae, described by Townes in 1960. It belongs to a large family of parasitoid wasps that are primarily internal or external parasites of other insects. The genus Eruga is part of the diverse ichneumonid radiation, though specific biological details for this particular species remain poorly documented in available literature.
Erythridula abolla
Erythridula abolla is a species of leafhopper in the family Cicadellidae, subfamily Typhlocybinae. It belongs to the tribe Erythroneurini, a group of small leafhoppers often referred to as "microleafhoppers." The species was described by McAtee in 1920. Like other members of its genus, it is likely a plant-sap feeder, though specific host plant associations remain poorly documented. Observations suggest it occurs in eastern North American deciduous forest and woodland edge habitats.
Erythridula clavata
Erythridula clavata is a species of leafhopper in the family Cicadellidae, subfamily Typhlocybinae. It was described by DeLong in 1916. Very little is known about its biology or ecology. Available records indicate it has been observed in Tennessee.
Erythrothrips keeni
Erythrothrips keeni is a predatory thrips species in the family Aeolothripidae, described by Moulton in 1929. As a member of Aeolothripidae, it belongs to a family characterized by predatory feeding habits. The species is known from North America, though specific ecological details remain poorly documented. Only two observations are recorded in iNaturalist, indicating it is rarely encountered or underreported.
Eucera cordleyi
Cordley's Long-horned Bee
Eucera cordleyi is a species of long-horned bee in the family Apidae, first described by Viereck in 1905. Like other members of the genus Eucera, males are characterized by exceptionally long antennae. The species occurs in North America and is part of the Eucerini tribe, which includes important pollinators of agricultural crops such as cucurbits. Specific ecological details for this species remain poorly documented.
