Excellent question.  Given that all 12 were very fresh males, and 
collected in a
roughly 10 foot circle in the middle of thousands of acres of identical 
its pretty clear the bug is in good shape.  For example, until recently,
"Biston" multidentata (Guedet 1941) [ MONA 6641 ] was known from 
roughly a dozen
total specimens, all but 2 females.  However, this year in the right 
habitat we
routinely saw 30-50 males, all of which flew just before sunset or just before
sunrise.  Again, much more common than thought, just that the normal sampling
methods, locations, and time only catch those few individuals that strayed
widely from their core habitat.

We are blessed here in SE Arizona with huge areas of habitat for almost 
all our
bugs.  If this was a small isolated hammock in S FLorida, we would have 
it very differently!
