Physical Characteristics

The banded hickory borer ranges in length from 15 to 35 mm, characterized by strong spines on the femora, pronotum, and on the tips of the elytra.

Identification Tips

Look for the distinctive spines and the size range of 15-35 mm. The species may be identified by its presence on hickory and oak trees.

Habitat

Typically found on hickory and oak trees.

Distribution

Found throughout the eastern half of North America, including Mexico and the Bahamas; one subspecies extends to the Sonoran Desert.

Life Cycle

Eggs are laid in crevices in the bark or directly into the wood. Larvae develop beneath the bark before boring deeper into the wood.

Ecosystem Role
