Not many caterpillars have been found in tree buds, except one crabapple tree in Kingston where I found one caterpillar in every other flower bud cluster today. Caterpillars are tiny and difficult to find at this time. Don’t bother looking for caterpillars now! Wait another week or two until caterpillars are bigger and easier to find
Did cold weather this past week kill caterpillars? I don’t think so, at least not in Washington County. I will check more locations next week. The cold temperatures did kill some apple and blueberry flower buds, but didn’t destroy the crop.
Now is not the time to spray to control winter moth caterpillars.
What a rotten start to the growing season!
