It is very localized, although of course it might spread. U-Mass extension
has a lot about it. I am smack in the center of it's Massachusetts range
It's not just an issue for fruit trees. It also likes several common shade
trees such as oak, and to a lesser extent, maple. I've seen (local) trees
completely defoliated by winter moth, and in november the emerging moths
are sometimes so numerous around my (commuter-rail) train station in the
evening that people bat them away from their faces.
Although all the literature says they also attack blueberries, I have
blueberries all over the place, including wild ones growing directly
beneath my (affected) oaks, and have never noticed winter moths or their
characteristic damage on them. And they have a strong preference for my
domestic apples over native crab apples. I have several branches of
domestic apple grafted to a crab, and despite spraying I always see moths
and damage to the domestic apples, and little damage to the crab part of
the same tree - even in years when I ran low on spray and only treated the
domestic apple portion of the tree.

>The alleged epidemic of winter moths in the northeast has me a bit
perplexed. I've always had a minor problem on some sites where trees with
a light flower set will loose the potential very light crop to some kind of
flower eating caterpillar. On the same sites trees with a heavy set are
unaffected by whatever reduction may be taking place. The problem just
isn't big enough to bother with.

"Fruit Grower News" the first published in Washington the other Michigan
and have never seen mention of this particular pest nor is it mentioned in
Cornell's "Pest Management Guidelines for Fruit Production" in the 2007
edition or earlier. Given the unique timing of its emergence it makes no
sense that it would be overlooked if it is such a potent threat. Can
anyone clear this up for me?
