That's interesting, I didn't know they pulled back the chlorophyll, thanks for the explanation!

Recently a few maples in our neighbourhood got infested with moths, one had all of its leaves eaten by mid-June. I thought it might kill the tree, but it popped out all of the empty leaf stems and simply regrew (smaller) the leaves. I always wondered what kind of energy expenditure it was for the tree to d o that, now it seems like more than I realized.
