Little Carpenterworm

A smaller relative of the carpenterworm moth that bores into oaks and other hardwoods. Larvae create long tunnels through the sapwood and heartwood.

💡

Did You Know?

Its tunnels reduce the commercial value of lumber and provide entry points for wood-decay fungi.

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.
