guess pruning worm was a local name. I'll be looking for
the insect with your description, now that I know what to 
look for. Plenty of wisteria and mimosa for them to girdle
around here. I was sure that the eggs were in one of the 
ends, but I had guessed wrong and was burning the cut-off
branchs. A Sherman tank, eh? You are dating yourself. I 
remember them also. Thanks again. Doc  (I need a Bazooka)
