My dad was having problems with something eating around the branches on his trees (mostly maple) and causing the branches to weaken or possibly fall.* He says they are called GIRDLE WORMS, where he got this name I'm not sure.** Anyway, he ask me if I could find any information about them.***The spelling may be wrong, or they might be*called something different entirely.* If anyone has an idea what might be doing this please let me know.*** Thanks.
