Dichelotarsus heteronychus
Crookedjaw Soldier Beetle
Dichelotarsus heteronychus is a species of soldier beetle in the family Cantharidae, originally described as Podabrus heteronychus by Fall in 1927. It is known from northern and western Canada. The common name 'Crookedjaw Soldier Beetle' suggests a distinctive mandibular feature, though detailed morphological descriptions remain limited in available sources. Like other Cantharidae, it likely exhibits soft-bodied elytra and predatory or omnivorous feeding habits as an adult.
Elaphrus lapponicus
Northern Peacock Beetle
Elaphrus lapponicus is a ground beetle species in the subfamily Elaphrinae, described by Gyllenhal in 1810. It belongs to a genus known for species that closely resemble tiger beetles (Cicindelinae), often leading to misidentification by collectors. The species has a Holarctic distribution, occurring across northern regions of North America and Eurasia. Like other members of Elaphrus, it likely inhabits moist, open habitats near water.
Helophilus lapponicus
Yellow-margined Marsh Fly
Helophilus lapponicus is a Holarctic species of hoverfly found across northern North America, northern Europe, Greenland, and Siberia. Adults are medium-sized syrphid flies, 12.5–13.5 mm in length, commonly observed visiting flowers for nectar and pollen. The species is distinguished by yellow abdominal markings and specific wing venation. Larval biology remains undocumented, though congeneric species develop in wet decaying organic matter.
Phanocelia canadensis
Phanocelia canadensis is a northern caddisfly in the family Limnephilidae, first described by Banks in 1924. The species has been documented at the southern extreme of its range, where studies have examined its habitat preferences and life history traits adapted to northern conditions. As a member of the Limnephilidae, it belongs to a diverse family of caddisflies whose larvae construct portable cases from plant material or sand.
