OK!! This was fascinating- but kind of gross at the same time!!!
This is a mass of web worms we found on our neighbor's Pecan tree.
We hadn't even noticed them- we were actually looking at the webs high in the branches of
the tree and checking the destruction of the leaves- when one my littles
said he had a discovery! This group of worms was near the bottom of the
tree and the caterpillars were then climbing and making their way
all over the tree!!!
