Please help identify
I have been searching the internet, trying to figure out what kind of bug this is. I know it’s some form of a true bug, but cannot pinpoint the species. Is it harmful to my trees, etc.? Thanks for any help you can provide.
These are Barklice, and they are in the order Psocoptera. They are not harmful to your trees. According to Eric Eaton, they probably feed on fungus spores which might make them beneficial to your tree.
