Last year I noticed these bugs appearing on a tree in my yard. This year there are MANY MANY MANY of them taking over the tree, and the snow JUST melted.
Cannot figure out what the bug is, or how to help stop it from killing this tree.
Thanks for your help,

Hi Jared,
We don’t know exactly where to begin looking to identify these green Beetles.  We have written to Eric Eaton for assistance.

Hi, Daniel:
Those *aren’t* woodborers.  They are “flea beetles,” probably in the genus Altica, family Chrysomelidae.  Perhaps they overwintered as adults.
