Ash tree and boxelder branches are prime feeding grounds for the larvae of the Ash-Tip Borer Moth.
The golden brown Ash-Tip Borer Moth has a trio of white spots on the upper half of each forewing. The middle spot is smaller than the outer two. A larger, lower white mark resembles a cracked egg with yolk running through the middle. Two single white dots sit near the furry thorax. They are active from late summer through autumn and are nocturnal.
Caterpillars of the Ash-Tip Borer are a type of cutworm thanks to their slicing ability and worm-like body. They cut into the soft stems and twigs of ash trees and boxelder bushes after hatching. They remain there, feeding on the host plant until they pupate.
