Twig Girdlers

Twig girdlers are small beetles that bore into shrubs and trees to lay eggs. The boring encircles the branch tip, hence the "girdler" name. Homeowners will probably notice dead branch tips on trees such as oak, hickory, pecan, and magnolia. Girdled limbs eventually break and fall to the ground, but the damage is usually not life threatening to healthy trees. Pruning dead or dying branches back to healthy wood is usually all that's required.
