Rebecca & everyone else:

I do think that in many places we are seeing excellent numbers of
butterflies this year.  I attribute this to several factors:

1. We're still in the post gypsy moth spraying recovery.  Gypsy moth
sprays, including Bt, knocked lots of butterfly populations way down.

2. The drought: most butterflies thrive in hot, sunny weather.  Heavy
summer rains actually kill a number of individuals.

3. The drought: many natural areas have seen earlier flowering for some
species, and other species haven't bloomed at all.  As a result,
butterflies are gathering in big numbers around tended butterfly
gardens, where they are finding nectar that's often unavailable in the
wild.

I haven't seen data from too many of the region's butterfly counts yet,
so I don't know if absolute numbers are really up substantially, or if
#3 above is the primary factor and we're just noticing greater
concentrations around certain areas.  It is fun, however: I saw 8
species in my suburban yard in 1/2 hour this afternoon.

Cheers,
