Absolutely true.  Not a small undertaking.  This was the kind of 
thing done with the Schaus project.  In addition to all John stated, 
you also need to do preliminary surveys of historical locations for 
the butterfly and plant species through known museum records.  There 
may still be some other sites out there.  Just an example of another 
very valuable use of collected specimens.  Leroy mentions that this 
thing was from at least 5 counties that he knew of.  That is some 
ground to cover.

Cheers,  Rich
