Aldrichia auripuncta
Aldrichia auripuncta is a species of bee fly in the family Bombyliidae, first described by Painter in 1940. It is known from the northeastern United States. As a member of Bombyliidae, it likely exhibits the family-characteristic parasitoid lifestyle, though specific details for this species remain limited.
Bucculatrix packardella
Bucculatrix packardella is a minute moth species in the family Bucculatricidae, described by Vactor Tousey Chambers in 1873. It is one of approximately 100 described species in the genus Bucculatrix, commonly known as ribbed cocoon-maker moths. The species is documented from the northeastern and north-central United States and adjacent Canada.
Cafius aguayoi
Cafius aguayoi is a species of rove beetle in the family Staphylinidae, described by Bierig in 1934. The species belongs to the genus Cafius, a group associated with coastal and intertidal habitats. Documented occurrences are limited to the northeastern United States.
Colladonus brunneus
Colladonus brunneus is a leafhopper species in the family Cicadellidae, first described by Osborn in 1915. It belongs to the tribe Platymetopiini within the subfamily Deltocephalinae. The species has been recorded from several northeastern and midwestern U.S. states.
Colladonus setaceus
Colladonus setaceus is a species of leafhopper in the family Cicadellidae, first described by Nielson in 1957. It belongs to the genus Colladonus, a group of leafhoppers found in North America. The species is recorded from the northeastern United States and adjacent Canada, with distribution records from Maine, New Hampshire, New York, Nova Scotia, and Québec. As with other members of its genus, it is likely associated with herbaceous vegetation and may serve as prey for certain wasp species.
Dasineura tumidosae
Ash Petiole Gall Midge
Dasineura tumidosae is a gall midge in the family Cecidomyiidae that induces galls on ash trees (Fraxinus spp.). The species is known primarily from its association with ash petioles, where larvae develop within characteristic swellings. Like other Dasineura species, it has a narrow host range tied to specific plant tissues. The midge has been recorded from the northeastern United States, particularly Vermont.
Eucosma verna
Speckled Eucosma Moth
Eucosma verna is a small tortricid moth described by Miller in 1971. It belongs to the large genus Eucosma, which contains numerous species of tortrix moths, many of which are associated with composite plants. The species is known from the northeastern United States, with confirmed records from Vermont.
Gyponana cacumina
Gyponana cacumina is a species of leafhopper in the family Cicadellidae, described by DeLong in 1942. Like other members of its genus, it produces brochosomes—complex protein-lipid nanoparticles that form a superhydrophobic, anti-reflective coating on its body and wings. The species has been recorded from multiple states in the northeastern United States and Arizona.
Papaipema polymniae
Cup Plant Borer, Leafcup Borer Moth
Papaipema polymniae is a noctuid moth commonly known as the Cup Plant Borer or Leafcup Borer Moth. The species is a specialist herbivore whose larvae feed exclusively on Polymnia uvedalis (leafcup), a native North American plant in the sunflower family. It has been documented in limited numbers in the northeastern United States.
Parhelophilus divisus
Yellow-legged Bog Fly
Parhelophilus divisus is a rare syrphid fly species known as the yellow-legged bog fly, documented primarily from the northeastern United States. The species exhibits the characteristic hoverfly ability to remain nearly motionless in flight. Adults are flower-associated, feeding on nectar and pollen, while larvae possess the distinctive long-tailed "rat-tailed" morphology typical of many Eristalinae.
Phyllobaenus caeruleipennis
Phyllobaenus caeruleipennis is a species of checkered beetle in the family Cleridae. The species name refers to its blue-winged appearance. Like other members of the genus Phyllobaenus, it is likely associated with fungal habitats and woodland environments where it preys on small arthropods. The species has been documented in the northeastern United States.
Sphegina rufiventris
Black-horned Pufftail
Sphegina rufiventris is a common syrphid fly species found in the northeastern United States. Adults are commonly observed on flowers, where they feed on nectar and pollen. The species is notable for its ability to hover nearly motionless in flight, a trait shared with other hoverflies. Larvae develop in specialized microhabitats, specifically accumulations of decaying sap under bark in moist environments.
Xanthia tatago
pink-barred sallow, pink-banded sallow
Xanthia tatago is a noctuid moth described in 2003, known by the common names pink-barred sallow and pink-banded sallow. The species belongs to the cutworm or dart moth group within Noctuidae. It is distributed across northern North America, with records from the Canadian Prairie provinces and the northeastern United States.
