Ellychnia corrusca
winter firefly
Ellychnia corrusca, commonly known as the winter firefly, is a diurnal beetle in the family Lampyridae that lacks bioluminescent organs as an adult. Adults are active during winter and early spring, overwintering on tree bark before mating in March through May. The species exhibits an unusual life cycle timing that separates its activity from nocturnal firefly predators. It is notable for its association with maple syrup production, where adults frequently enter sap collection buckets.
Glycobius speciosus
Sugar Maple Borer
Glycobius speciosus, commonly known as the sugar maple borer, is a small longhorned beetle in the tribe Clytini. It is the sole species in its genus. The species is a specialist wood-borer whose larvae develop in living sugar maple trees, causing significant damage to the host. Adults are active in spring and early summer and are attracted to ethanol-based baits. The species is distributed across northeastern North America, from Canada through the northeastern United States.
