What to blame

[Michael Gochfeld]

I agreed entirely with the first part of Ron's message on Butterflies 
and Weather.  He also wrote: 


"So if there is a big drop next year don't blame it on spraying, over
collecting, etc. "blame" (attribute) it to an unhealthy out of balance
population explosion the season before - and see it as nature simply
bringing populations back to normal levels."
				****
Actually spraying produces a big drop this year (particularly in 
univoltines). Whether it is apparent next year depends on phenology and 
whether there are early life stages hidden away.
