Reply to comment by Highwaymantechforcer in Is there an evolutionary reason behind deciduous trees’ vibrant fall colours? by Team_Ed

We had a major spongy moth caterpillar problem this year, hitting mostly oak, but our crabapple and a few other trees as well. All refoliated. I had wondered about the metabolic costs and trade-off, thanks.

I forgot one exception. We have a white oak, and I've been told that they're wonderful trees to have. So I worked hard at keeping it clear of caterpillars, with some success. It partially refoliated where there was more damage, but kept on with the lightly damaged leaves. An interesting question in how much damage calls for refoliation.
