What causes this in maple?

[PartTimeJack]

Heard it's beetles, or worms of some kind, that cause these black streaks. Is that correct, and is there still any lumber value in it with the black streaks?

Ambrosia beetle most likely. I like it.

If woodturners weren't such cheap skates, Ambrosia Maple would have high value. They love to turn it, hate to pay for it. But in a log that size, maybe it would be worth a shot to look some up.

The streaks are caused by the trees reaction to being attacked by the ambrosia beetle.  Hence, the name, ambrosia maple.  It can be strikingly beautiful wood.

Danny, 


Do you know the scientific name of the Ambrosia beetle? 

I've previously attempted to research them, but have not learned much.

Very interesting, Thank you for the replies. 

Got about 6 logs of this size with the marking. Diffidently going to look for a buyer, or may have it milled my self.

I really like the affect the beetles leave.  I would think you would want to keep it or sale for good money.

I thought that was just the wood turners around here!
