OK Gang,
Hoping one of you can help me out. This morning while investigating a lighting issue I noticed that all of the trees on this site have holes bored in the trunks. It literally looks like they were victims of a small caliber drive-by shooting, just riddled with holes (Not totally out of question; this is Chicago after all). The little white dots look like larvae to me (waiting to wreak havoc this spring?).
Both the pines and (Maples, Ash or Lindens? [too distracted by holes to get a good ID]) have these holes. All of the trees are affected and there are not just a few holes, they are dense and go all the way up the trunks. The main difference is that on the deciduous trees the holes are arranged perfectly, like rings around the trunk (or rosy as the case may be for these trees) while on the pines, the holes are more random.
Do any of you know what this is? Is it two different insects based on different trees and different hole patterns? What am I looking at here…?
Thanks for your help!
