Dear Listers,
Been a while since I gave any sort of field report, so I'll
try to make up for it. As I said recently, few Monarchs, but we are
having good flights of P. sennae, E. lisa, P. ocola and U. proteus.
Recently, I made a couple of trips out to a site on the
west side of Pigeon Mountian, west of LaFayette in Walker Co., in NW
GA. Two lep species are having flights like I have never witnessed
before. The White M Hairstreak (Parhassius m-album) is flying in
huge numbers. I probably saw at least a couple of hundred specimens,
when I'm used to seeing less than ten in an entire year. Also out in
tremendous numbers is the lovely orange and black day-flying
lithosiine arctiid Lycomorpha pholus, which again I am used to seeing
in batches of five to ten. I've probably seen close to a thousand in
the two days I've visited this site. Also impressive is the flight
of the Snout Butterfly (Libytheana bachmanii), as well as a healthy
flight of the Great Purple Hairstreak (Atlides halesus), along with
several Swallowtail species and several other Sulphur species. Gray
Hairstreaks (Strymon melinus) and Red-Banded Hairstreaks (Calycopis
cecrops) are also flying strong.
On the moth front, the first Virgo Tiger Moth (Grammia
virgo) and Intermediate Tiger Moth (G. parthenice intermedia) of the
season showed up Saturday night, as well as two new state records for
Georgia, the noctuids Sutyna privata and a Papaipema near
arctivorens (when it's off the boards, Eric, I'll send it your way).
Several Underwings (Catocala) are now flying, after a
generally bad year for most species; these include C. carrissima,
vidua, lacrymosa, insolabilis, and a couple of others that were not
viewed close up. For you geometrid enthusiasts, there is a nice
flight of Caripeta aretaria going on right now. All in all, shaping
up to be a real nice fall season here in N. Georgia, with the
possible exception of the lack of Monarchs.
