Calaphis neobetulella
Blotched River Birch Aphid
Calaphis neobetulella is an aphid species described by Quednau in 1971, commonly known as the Blotched River Birch Aphid. It belongs to the genus Calaphis within the subfamily Calaphidinae. The species has been documented in very few iNaturalist observations, suggesting it may be uncommon, geographically restricted, or under-recorded. As a member of the Aphididae, it is a sap-feeding insect likely associated with birch host plants.
Oncopsis flavidorsum
Oncopsis flavidorsum is a species of leafhopper in the family Cicadellidae. It has been documented in northeastern North America, with records from New Hampshire, New York, Pennsylvania, Newfoundland and Labrador, and Nova Scotia. The species was originally described by Amyot and Audinet-Serville in 1843. Like other Oncopsis species, it is associated with birch (Betula) host plants.
Symydobius
Symydobius is a genus of aphids (Hemiptera: Aphididae) in the tribe Calaphidini. Species occur in Europe and North America, with at least two described species: S. alniarius and S. americanus. The genus is associated with birch (Betula) hosts. Symydobius oblongus exhibits behavioral coordination with attending ants, specifically Formica lugubris.
