Re: What makes holes in walnut trees?

This morning I notied a couple of sap weeps on the trunk of
a seedling walnot tree planted about fifteen years ago. It
looks like something chewed holes in the trunk about two feet
above the ground, leaving a residue of cuttings in the entrance
hole and a bit of sap around it, with the excess dripping down.

If anybody recognizes the pattern I'd be curious to know
what it is. The tree seems healthy, at least for now.

  1st one looks like only mild damage to the bark without any
actual bore hole.  the other it looks like there is debris or
frass from chewing indicating perhaps a bug ate inwards or
perhaps someone was shooting a bbgun and hit your tree.
exploring that hole might give some more information...

  IMO trees are sturdy and can recover from damage of this
sort but if you do have an actual bug in there it would be
probably better to make sure it is dead and gone and then
the tree can heal over the wound.
