FW: What happened to our biggest moths?

[Michael Gochfeld]

Question to Jeff Boetner or anyone else. 

How effective were the flies in controlling either Tent Caterpillars or 
Gypsy Moths.   Tent Caterpillars here (NJ) seem to be influenced more by 
how cold the winter gets  (not very cold in most recent years) and Gypsy 
Moths came and went and elicited heavy spraying suggesting the 
biological control was not very effective.
