Dioryctria banksiella
Dioryctria banksiella is a species of snout moth in the family Pyralidae, described in 1969 from Canadian specimens. The larvae develop within galls formed by the western gall rust fungus (Cronartium harknessii) on jack pine (Pinus banksiana) trunks. Early instars feed on gall tissue beneath the bark, while later instars mine deeper into the gall. The species is known only from western and central Canada.
Diphyus apiculatus
Diphyus apiculatus is a species of ichneumon wasp described by Walkley in 1958. It belongs to the family Ichneumonidae, one of the largest families of parasitoid wasps. The species has been recorded from multiple localities in Alberta, Canada. As a member of Diphyus, it likely functions as a parasitoid of other insects, though specific host records for this species remain limited.
Diphyus provancheri
Diphyus provancheri is a species of ichneumon wasp in the family Ichneumonidae, described by Cushman in 1925. The genus Diphyus belongs to the subfamily Ichneumoninae, a large group of parasitoid wasps. Records indicate this species has been documented in the Edmonton region of Canada. Like other members of its genus, it is presumed to be a parasitoid, though specific host associations remain undocumented.
Diplolepis rosaefolii
Diplolepis rosaefolii is a gall wasp in the family Cynipidae that induces distinctive lenticular (lens-shaped) galls on the leaves of rose plants across Canada. The species exhibits an alternation of generations life cycle typical of cynipid wasps, with a bisexual spring generation producing the visible galls and an agamic (asexual) winter generation of wingless females. In Ontario and Quebec, it is primarily associated with native Rosa acicularis, though populations have been documented on the cultivated hybrid rugosa shrub rose 'Thérèse Bugnet'. The galls support a diverse component community including multiple parasitoid wasp species and inquilines.

The species is documented from western North America, with records from Alberta, Canada. Like other Epinotia species, it is likely associated with coniferous hosts, though specific biological details remain poorly documented in published literature.
Epinotia rectiplicana
Epinotia rectiplicana is a species of tortricid moth in the family Tortricidae, first described by Walsingham in 1879 under the basionym Paedisca rectiplicana. It belongs to the tribe Eucosmini within the subfamily Olethreutinae. The species is documented from the Canadian prairie provinces of Alberta, Manitoba, and Saskatchewan.
Epinotia xandana

Epiphanis cornutus
false click beetle
Epiphanis cornutus is a species of false click beetle in the family Eucnemidae. The species occurs across Europe, including the British Isles, and in North America. As a member of Eucnemidae, it belongs to a group of beetles commonly known as false click beetles, which are distinguished from true click beetles (Elateridae) by subtle morphological differences. The specific epithet 'cornutus' refers to horned or horn-like features, though detailed morphological descriptions of this particular species are limited in available sources.
Epirrhoe plebeculata
Orange-winged Carpet
Epirrhoe plebeculata, commonly known as the Orange-winged Carpet, is a geometrid moth in the family Geometridae. It is distributed across North America, with confirmed records in Alberta and Saskatchewan, Canada. The species was first described by Guenée in 1858 and is recognized by MONA/Hodges number 7395. Two subspecies are recognized: E. p. plebeculata and E. p. vivida.
Epirrhoe sperryi
Sperry's Argent & Sable, small argent and sable
Epirrhoe sperryi is a geometrid moth in the subfamily Larentiinae, found in North America. The species is known from the Canadian prairie provinces of Alberta, Manitoba, and Saskatchewan. It belongs to a genus characterized by black-and-white patterned forewings, though specific diagnostic features for this species remain poorly documented in published literature.
Epuraea truncatella
Epuraea truncatella is a species of sap-feeding beetle in the family Nitidulidae. The species was described by Mannerheim in 1846. It is found in North America, with records from multiple Canadian provinces including Alberta, British Columbia, and Labrador. As a member of Nitidulidae, it is associated with fermenting plant materials and sap flows.
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.
