Al, Thanks for the link, very interesting article.
I've sawn many board feet of ambrosia maple over the years. It makes beautiful paneling. In fact, I paneled my shop with it.
I have several thousand board feet of curly ambrosia maple in my shop just waiting for the right project.
Here are some pictures of another kind of maple that gets attacked and has simular markings, except the holes and stains are bigger.
Unlike soft maple which gets attacked by the ambrosia beetle, this maple gets attacked in late winter by the homo sapien sap seeking borer.
Instead of feeding on fungus, this borer collects the tree's sap and renders it into a sweet nectar.
Here are a couple of pictures in case you've ever wondered what tapping maple trees does to the lumber.
This borer is a bane to loggers and sawmillers!
