Dear Jonathan,
Since neither the church nor the state recognizes marriage between “bugs” or any other lower beasts for that matter, these Barklice or Tree Cattle cannot have been conceived out of wedlock.  Though they look potentially problematic, Tree Cattle are benign creatures that feed on lichen and fungus, and they will cause no harm to your trees, neither ash nor oak nor any other species.

Dear Daniel,
Please excuse my late reply. Many thanks for this information!
Have a great weekend,
Jonathan Bowie
