Acronicta lepusculina
Cottonwood Dagger Moth, Cottonwood Dagger
Acronicta lepusculina, commonly known as the cottonwood dagger moth, is a noctuid moth species first described by Achille Guenée in 1852. Adults have a wingspan of 40–50 mm and are active from May to July. The species is notable for its larval association with woody plants in the genera Salix, Populus, and Betula.
Agromyza alnibetulae
Agromyza alnibetulae is a leaf-mining fly in the family Agromyzidae. The species is associated with alder (Alnus) and birch (Betula) host plants, as indicated by its specific epithet. Larvae create serpentine or blotch mines in leaves. Adults are small, typically 2-3 mm in length, with the reduced wing venation characteristic of the genus.
Apagodiplosis papyriferae
Apagodiplosis papyriferae is a species of gall midge in the family Cecidomyiidae, described by Gagné in 1967. The specific epithet papyriferae indicates an association with paper birch (Betula papyrifera). As a member of the gall midge subfamily Cecidomyiinae, this species likely induces gall formation on its host plant, though specific gall morphology has not been documented in available sources. The genus Apagodiplosis contains relatively few described species, and most remain poorly studied.
Drepana
hook-tip moths
Drepana is a genus of hook-tip moths in the family Drepanidae, subfamily Drepaninae. The genus includes species with distinctive falcate (sickle-shaped) forewings that give the group its common name. Larvae are folivorous, feeding primarily on birch and alder. Some species exhibit notable vibrational communication behaviors during larval territorial contests. Adults are nocturnal and fly primarily in spring and summer.
Epinotia solicitana
Birch Shootworm Moth
Epinotia solicitana is a small tortricid moth commonly known as the Birch Shootworm Moth. The species is recognized for its association with birch trees as a larval host, with larvae feeding internally on shoots and causing characteristic damage. Adults are typically active during summer months across northern North America. The species has been documented from Alberta, Manitoba, and Vermont, with additional records likely across the broader boreal and northern temperate regions of the continent.
Erythridula noeva
Erythridula noeva is a leafhopper species in the family Cicadellidae, subfamily Typhlocybinae, originally described as Typhlocyba obliqua var. noevus by Gillette in 1898. It belongs to the subgenus Erythridula within the larger genus Erythroneura. The species has been documented on birch hosts in New Brunswick, Canada, where it exhibits similar seasonal histories and habits to other Erythridula species but differs in host relationships and ecology. It is one of five Erythridula species studied from birch in that region.
Euura poecilonota
Marbled Birch Nematine
Euura poecilonota is a species of sawfly in the family Tenthredinidae, commonly known as the Marbled Birch Nematine. It belongs to the large and diverse genus Euura, which comprises numerous species associated with willows and other woody plants. The species was originally described by Zaddach in 1876 under the name Nematus poecilonotus. Like other nematine sawflies, this species is likely associated with birch (Betula) as a host plant, though specific biological details remain poorly documented in available literature.
Phratora hudsonia
birch leaf beetle
Phratora hudsonia is a small leaf beetle in the family Chrysomelidae, commonly known as the birch leaf beetle. It is found in North America, with documented populations in Ontario, Canada, as well as Alberta, British Columbia, and Manitoba. The species feeds exclusively on birch leaves and has been the subject of biological study focusing on its seasonal occurrence, habits, and immature stages.
Phyllonorycter martiella
Phyllonorycter martiella is a micro-moth in the family Gracillariidae, known from eastern North America. Adults are extremely small with a wingspan of approximately 6.8 mm. The species is a leaf-mining specialist, with larvae feeding on birch species.
Trypodendron betulae
birch ambrosia beetle
Trypodendron betulae, the birch ambrosia beetle, is a North American ambrosia beetle in the family Curculionidae. It attacks standing stressed sub-canopy birch trees, particularly paper birch (Betula papyrifera). Male and female pairs construct galleries in sapwood where they cultivate symbiotic Ambrosiella fungi for larval nutrition. The species has a female-produced aggregation pheromone blend of (3S,6R)-trans- and (3R,6R)-cis-linalool oxide pyranoid, which chemically isolates it from sympatric Trypodendron species. Adults emerge in September and overwinter in leaf litter.
