What could be boring into this tree?
Hello-I think this problem has come up before but I couldn’t find the thread-wish I’d paid attention now! It looks as though something is boring a hole at the base of one of my trees:

There is a small pile of shavings On the ground. I noticed it last year too but hoped it would go away. Does anyone know what it could be?
thanks
