Emerald Ash Borer Galleries

 
I suspect pretty much everyone has heard about the devastation the emerald ash borer is bringing about. Here's one example of a tree that has come to a sad end.

It's amazing how a little beetle can eat all the critical tissue just under the bark. See how it's completely separated.

Here's a closer look at the galleries left by the borer. It's interesting how they are not symmetrical at all, the way the elm bark beetle galleries are.

I'm really worried about those bugs arriving here. We have lots of ash trees; they're the most common young sapling that comes up on old fields.

We had two dozen ash trees planted in two parallel rows that are now dead because of this terrible pest.

I hope the ash trees make a comeback like the elm trees have done.
