Bombus insularis
Indiscriminate Cuckoo Bumble Bee
Bombus insularis is a cuckoo bumble bee in the subgenus Psithyrus, native to northern and western North America. As a social parasite, it invades nests of host bumble bee species, usurps the resident queen, and exploits host workers to rear its own offspring. The species is known for its broad host range, attacking multiple bumble bee species across diverse habitats including tundra, taiga, and mountain ranges.
Bombylius pulchellus
Beautiful Bee Fly
Bombylius pulchellus is a species of bee fly in the family Bombyliidae, distributed across northern North America from Canada to the northern United States. Adults are active in spring and are known for their parasitoid relationship with the sweat bee Halictus ligatus, whose larvae and pupae they consume. Unlike many bee flies, B. pulchellus pupates in soil away from the host nest rather than within it.
Chalcosyrphus inarmatus
Yellow-haired Leafwalker
Chalcosyrphus inarmatus, commonly known as the yellow-haired leafwalker, is an uncommon species of syrphid fly distributed across northern North America. The species belongs to a genus whose larvae are typically associated with decaying wood rather than the aphid predation common to many hover flies. Adults are flower visitors that obtain nectar and pollen from floral resources.
Eucnecosum brunnescens
Eucnecosum brunnescens is a rove beetle in the family Staphylinidae, subfamily Omaliinae. The species was originally described by Sahlberg in 1871 under the genus Arpedium, and later transferred to Eucnecosum. It has a Holarctic distribution, occurring across northern Europe, Russia, and North America from Alaska through Canada to the northern United States.
Gnorimoschema septentrionella
A small gelechiid moth described by Fyles in 1911. The species is known from northern and north-central North America, with records spanning Canada and the northern United States. Larvae are gall-formers on Aster junceus. Wingspan approximately 20 mm.
Melissodes rivalis
rival long-horned bee, Western Thistle Longhorn Bee
Melissodes rivalis is a solitary long-horned bee in the family Apidae, native to northern North America. Males are distinguished by antennae that may exceed their body length. Females construct individual underground nests and provision them with pollen, while males form sleeping aggregations on flower heads. The species has been documented pollinating thistles (Cirsium sp.).
Parhelophilus porcus
black bog fly
Parhelophilus porcus, commonly known as the black bog fly, is an uncommon syrphid fly species recorded from northern North America. Adults are flower-visiting insects that obtain nectar and pollen from blooms. The species possesses the rat-tailed larval form characteristic of related aquatic or semi-aquatic hoverflies, with an elongated breathing siphon.
Polopeustis arctiella
Polopeustis arctiella is a small snout moth in the family Pyralidae, described by Gibson in 1920. It is restricted to northern North America, with records from the Canadian provinces of Alberta and Manitoba, as well as the territory of Nunavut. The species has a wingspan of approximately 22 mm. It belongs to the subfamily Phycitinae, a diverse group of pyralid moths whose larvae often feed on stored products or plant materials.
Scopula junctaria
Simple Wave
Scopula junctaria, commonly known as the simple wave, is a moth species in the family Geometridae. First described by Francis Walker in 1861, it is widely distributed across northern North America, occurring throughout Canada and extending southward into the northern United States. Adults are active from late May through August, with a single generation per year. The species is characterized by its relatively small size and distinctive wing pattern.
