  • Caterpillars have a red-orange head with two sets black tufts near the head; yellowish hairy body with distinct tufts of hair resembling a toothbrush on top of the body

Deer feeding/antler rubbing

  • Long lines of shredded or peeled off bark along main trunk up to 3 feet off the ground from antler rubbing
  • Feeding occurs from the ground up to 6 feet or slightly higher. Ragged edges, same as above, also if the bark is removed by a deer there will be no teeth marks
  • Wood may appear shiny or "polished"
  • Leaves and small branches (>1 inch diameter) cut off with a rough or ragged edge (Not a clean cut!)
  • Damage is common only on young trees, old trees have thick bark and wide stem so are not used by deer for antler rubbing
