Quick Summary

The ribbed pine borer (Rhagium inquisitor) is a type of long-horned beetle, belonging to the insect order Coleoptera. These beetles are characterized by their extremely long antennae. The larvae of the ribbed pine borer bore into pine trees.1

Long-horned beetles, including the ribbed pine borer, can be significant pests to timber, landscape, and fruit trees due to their wood-boring habits. The larvae, often called roundheaded borers, feed within woody plants for one to two years before pupating inside the tree and emerging as adults.1
