Beet Armyworm

A small grayish-brown moth whose green caterpillars attack a wide range of vegetable and field crops. Larvae often skeletonize leaves before moving to fruits and growing points.

💡

Did You Know?

Young larvae spin fine silk threads that allow them to balloon on the wind to new host plants.

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.
