Crambus youngellus
Young's Grass-veneer
Crambus youngellus, known as Young's Grass-veneer, is a small moth species in the family Crambidae. It was described by William D. Kearfott in 1908. The species is restricted to northeastern North America, with records from the northeastern United States and southern Ontario. As a member of the grass-veneer group, it likely shares ecological associations with grasses and sedges typical of the genus Crambus, though specific natural history details remain poorly documented.
Eratoneura ligata
Eratoneura ligata is a species of leafhopper in the family Cicadellidae, first described by McAtee in 1920. It belongs to the subfamily Typhlocybinae and tribe Erythroneurini. Like other members of its genus, it produces brochosomes—nanoparticles that create a superhydrophobic, anti-reflective coating on its body. The species has been documented in northeastern North America with observations from the District of Columbia, New Hampshire, Ohio, Québec, and Vermont.
Eratoneura mira
Eratoneura mira is a leafhopper species in the family Cicadellidae, subfamily Typhlocybinae, described by Beamer in 1932. Like other leafhoppers in this genus, it is a small, plant-feeding insect. The species has been documented in the northeastern United States. Leafhoppers in this family are known for producing brochosomes—nanoparticles that coat their bodies for waterproofing and anti-reflective properties.
Eratoneura parallela
Eratoneura parallela is a species of leafhopper in the family Cicadellidae, subfamily Typhlocybinae, described by McAtee in 1924. Like other members of the genus Eratoneura, it is a small, plant-feeding insect. The species has been recorded in the northeastern United States, specifically in Massachusetts and New Hampshire. As a typhlocybine leafhopper, it likely shares characteristics with congeners including the production of brochosomes—microscopic, hydrophobic proteinaceous spheres that coat the cuticle.
Eratoneura unica
Eratoneura unica is a leafhopper species in the family Cicadellidae, subfamily Typhlocybinae. Like other members of its genus, it possesses brochosomes—complex protein-lipid nanoparticles produced in the Malpighian tubules and distributed across the cuticle using comb-like hind leg spines. These structures render the exoskeleton superhydrophobic and anti-reflective. The species has been documented in the northeastern United States.
Eris rufa
Eris rufa is a species of jumping spider in the family Salticidae, first described by Carl Ludwig Koch in 1846 as Plexippus rufus. The species was transferred to the genus Eris in 2004 when G. B. Edwards synonymized it with the previously described Eris pinea. It occurs in northeastern North America, with documented records from Canada and the United States. The specific epithet rufa refers to the reddish coloration of this small spider, with females measuring approximately 5.9 mm and males 5.7 mm in total body length.
Erythridula bitincta
Erythridula bitincta is a species of leafhopper in the family Cicadellidae, subfamily Typhlocybinae. It belongs to the tribe Erythroneurini, a group of small, often colorful leafhoppers commonly referred to as microleafhoppers. The species was described by McAtee in 1926. Records indicate it occurs in northeastern North America, including parts of Canada and the northern United States.
Eutettix borealis
Eutettix borealis is a leafhopper species in the family Cicadellidae, described by Hepner in 1942. The species is known from limited distribution records in the northeastern United States. As a member of the tribe Platymetopiini, it belongs to a group of leafhoppers whose biology and ecology remain poorly documented in published literature.
Hoplistoscelis pallescens
damsel bug
Hoplistoscelis pallescens is a small predatory true bug in the family Nabidae, commonly known as damsel bugs. Adults measure less than 12 millimeters in length.

Like other members of this genus, it is likely a small to medium-sized bee with nesting habits typical of ground-nesting halictids. The species is known from limited observations, primarily from Vermont in the northeastern United States.
Lemmeria digitalis
Fingered Lemmeria Moth
Lemmeria digitalis is a moth species in the family Noctuidae and the sole member of its monotypic genus.

It belongs to the order Plecoptera, an ancient group of aquatic insects commonly known as stoneflies or springflies. The species is known from a limited number of observations and has a documented distribution in the eastern United States and southeastern Canada.
Marmopteryx
Marmopteryx is a genus of moths in the family Geometridae, established by Packard in 1874. The genus is currently considered a synonym of Stamnodes, with its type species Marmopteryx morrisata (Hulst, 1887) now placed as Stamnoctenis morrisata. The genus is known from a single species originally described from the northeastern United States.

Proctacanthus philadelphicus, commonly known as the northeastern marauder, is a species of robber fly in the family Asilidae. As with other members of the genus Proctacanthus, this species is a large, predatory fly. Robber flies in this genus are characterized by their prominent facial beards and aggressive hunting behavior. The specific epithet 'philadelphicus' suggests an association with the Philadelphia region, indicating part of its geographic range.

Rudiloria trimaculata is a flat-backed millipede in the family Xystodesmidae, recognized by the proposed common name Bob's Yellow and Black Millipede. The species occurs in the northeastern United States and southeastern Canada. Two subspecies are recognized: R. t. trimaculata and R. t. tortua.
Zapatella
Zapatella is a genus of gall wasps in the family Cynipidae. The genus includes at least one well-documented species, Z. davisae, which has become a significant pest of black oak (Quercus velutina) in the northeastern United States. Gall wasps in this genus induce gall formation on oak hosts. The genus was described in 2012 by Pujade-Villar & Melika.
Zapatella davisae
black oak gall wasp
Zapatella davisae is a cynipid gall wasp (Hymenoptera: Cynipidae) described in 2016 that has become a significant pest of black oak (Quercus velutina) in the northeastern United States. Larvae develop under bark in late summer, with adults emerging in early spring. The species has undergone notable population outbreaks on Long Island, NY (first documented 1990), Cape Cod and Martha's Vineyard, MA (2008), and more recently in coastal Rhode Island and Nantucket, MA. High parasitism rates by Sycophila species can lead to rapid population collapse, as observed on Long Island in 2016.
