Anthonomus morulus
Anthonomus morulus is a species of weevil in the family Curculionidae, described by John Lawrence LeConte in 1876. It belongs to the large genus Anthonomus, which contains numerous species associated with various host plants. The species is recorded from North America, though detailed biological information remains limited. As with many Anthonomus species, it is likely associated with specific plant hosts, but these relationships have not been well documented.
Anthophora mortuaria
Anthophora mortuaria is a solitary digger bee in the family Apidae, described by Timberlake in 1937. As a member of the genus Anthophora, it shares characteristics with other digger bees that nest in soil or sandy substrates. The species is accepted in taxonomic databases but has minimal published biological information available. Its specific epithet "mortuaria" (Latin for "of the dead" or "funeral") suggests possible association with particular habitats or behaviors, though this has not been documented in accessible literature.
Anthrax nigriventris
Anthrax nigriventris is a species of bee fly (family Bombyliidae) described by Marston in 1970. The species is characterized by its dark ventral coloration, as indicated by the specific epithet 'nigriventris' (meaning 'black-bellied'). Like other members of the genus Anthrax, it is presumed to be a parasitoid of ground-nesting insects, though specific host records for this species have not been documented. The species occurs in arid and semi-arid regions of the southwestern United States, Mexico, and Cuba.

Anticlea switzeraria is a species of moth in the family Geometridae, subfamily Larentiinae. It was described by Wright in 1916. The species is poorly documented in scientific literature, with minimal published information on its biology and ecology. It belongs to a genus of small to medium-sized geometrid moths primarily found in northern regions.
Anurapteryx crenulata
Crenulatewinged Grasshopper
Anurapteryx crenulata is a moth species in the family Sematuridae, originally described from North America. The species was previously classified under the grasshopper genus Cordillacris as C. crenulata, but has since been reclassified to the moth genus Anurapteryx. Very little biological information is available for this species under its current taxonomic placement. Most detailed ecological and behavioral data in the literature refers to the species under its former grasshopper classification.
Aoplus thujarum
Aoplus thujarum is a species of ichneumon wasp described by Heinrich in 1961. It belongs to the large parasitoid wasp family Ichneumonidae. The species name "thujarum" suggests an association with Thuja (arborvitae or cedar) trees, likely indicating host plant or habitat specificity. Very few observations of this species have been documented, with only one record in iNaturalist.
Apallates coxendix
A small grass fly in the family Chloropidae, originally described as Oscinis coxendix by Fitch in 1856 and later transferred to the genus Apallates. The genus Apallates is a small group within the Oscinellinae, and species-level biology remains poorly documented. The specific epithet 'coxendix' refers to the coxal region of the leg. Known from very few observations.
Aphalara persicaria
Aphalara persicaria is a species of psyllid (jumping plant louse) in the family Aphalaridae, first described by Caldwell in 1937. The species epithet "persicaria" suggests a possible association with plants in the genus Persicaria (knotweeds), though specific host relationships remain undocumented. It belongs to a genus of small, sap-feeding insects that are poorly studied in North America. Records indicate presence in Cuba and Ohio, USA.
Aphelia
Aphelia is a genus name with multiple unrelated applications across biological and non-biological domains. In zoology, Aphelia is a genus of tortricid moths (family Tortricidae, order Lepidoptera). In botany, Aphelia is a genus of monocot plants in the family Restionaceae (order Poales), with authority R.Br., 1810. The name also appears in astronomy as the plural of aphelion, referring to the points in solar orbits most distant from the Sun. This record addresses the biological taxa only; the astronomical usage is nomenclaturally coincidental.
Aphis pawneepae
Aphis pawneepae is a species of aphid in the family Aphididae, described by Hottes in 1934. The species is currently accepted in taxonomic databases, though some sources list it as a synonym. Very little is known about its biology, ecology, or distribution.
