Hi, Dave-
If you can get a close look at the damaged leaves, you should check for
the characteristic "shot" holes made by the adult beetles. They are
about 1mm or less in diameter, and are, if not absolutely diagnostic, at
least a very good indication that the tree is under attack by Orchestes
fagi.

   Went out at dawn to haul a load of firewood, thus beating the heat
a bit, and the route from tier to truck took me past a Hazelnut bush
and a young Beech (~15' tall). Both had about the same degree of leaf
browning. I wonder if some of the leaf discoloration which is being
attributed to the beetle is just wind burn.
