What Has Killed My Ornamental Tree This Year?

Question

This tree has red berries that birds do NOT eat. This spring it came into full leaf then leaves began to turn brown, wither and fall off. I found a small larva in great numbers on every leaf. I sprayed with soap and water but it was too late. The tree stands now 12 feet high without a leaf.

Answer 1

Not knowing what kind of tree it is, I can only speculate. But if the larva caused it to defoliate, it should regrow. Caterpillars rarely kill a tree. Be vigilante when it regrows and start treatment early if you see any more critters.
