Paucity of butterflies

[Michael Gochfeld]

New Jersey is experiencing very low numbers of butterflies, and its not 
because of drought.  We had extremely heavy rains for nearly two weeks. 

In thinking back over the last few years, we seem to have a post hoc 
excuse for everything that happens to butterfly numbers: too hot, too 
cold, too wet, too dry,  to warm a winter,  too much snow, not enough 
snow, etc.  It would be really nice to systematize information over 
large areas for a number of years.
