Zimmerman Pine Moth

Zimmerman Pine Moth
The larvae of the Zimmerman Pine Moth damages trees by tunneling just beneath the bark of the trunk and branches, most commonly on the trunk just below a branch. The tunnels they make can girdle the trunk or branches or physically weaken them so they are easily broken by wind or snow. Heavily infested trees are often deformed and sometimes succumb to the pest, which usually emerges in August in Nebraska.
