Raspberry Cane Borer
A slender black longhorn with two prominent yellow spots on the pronotum, found across North America. It is a significant pest of cultivated raspberries and blackberries. Females girdle canes with two rings of punctures before ovipositing.
Did You Know?
The double girdle cut by the female causes the cane tip to wilt, creating optimal moisture conditions for the egg to hatch.
Rough-Skinned Diving Beetle
A large diving beetle of northern and alpine regions across Europe and Asia. Both sexes have finely sculptured elytra, distinguishing it from the great diving beetle.
Did You Know?
It is one of the few large predatory beetles adapted to survive the extreme cold of subarctic lakes.
