Oaktree borers are a type of beetle that targets oak trees, especially stressed or damaged ones. They reproduce by depositing their eggs within the tree’s bark. Upon hatching, the larvae start consuming the inner bark and sapwood of the oak tree. The actions of these larvae sabotage the tree’s structural integrity and tree’s demise.

Some of the common types of oak tree borers are:

  1. The Red Oak Borer (Enaphalodes rufulus)– These long-horned beetles target live oak trees, causing cosmetic damage to the trunk and branches. The red oak borer has a two-year life cycle.
  2. Oak Pinhole Borer (Platypus cylindrus)– This small beetle attacks oak trees and other hardwood tree species.
  3. Gold-Spotted Oak Borer – Agrilus auroguttatus is native to the oak forests of Southeastern Arizona. It feeds on the sapwood and phloem.
  4. Two-lined Chestnut Borer (Agrilus bilineatus)- This beetle attacks red, black, white, and bur oaks, causing discolored foliage and wilting of branches.
