    We have a weeping willow tree, about 5 years old and has been growing very well. This year, I noticed a rather large black spot on one of the main limbs and now, there is a sizable hole that has developed. Today I found 2 large beetles near the sight; about 1/2 long, with the main body black and a yellow outlined head, with a black center. Can you give me some ideas as to what might be going on and what if any remidies I might have. There does not appear to be any distress on the tree as of yet, so I’m hoping that whatever is going on I can get to it before it affects the tree. Thanks so much. Tom Junkert

      Hi Tom. Thanks for the question. I suggest you post it to the discussion board instead of here though, as that page will get far more traffic. The discussion board is at http://discuss.myminnesotawoods.org/.
