A large wood eating beetle with characteristically long antennae giving rise to its common name

Common Name: Longhorn Beetle

The Longhorn beetle has been found eating dead trees at Hill Cove and Teal Inlet. It has been accidentally introduced to the Islands from southern Chile or Argentina.

Luckily for us, this species prefers to eat dead trees but some species can be serious pests, causing severe damage to living trees or timbers used in construction. The Asian long-horned beetle is one of the most destructive non-native insects in the United States.
