ENV: Big Springs 20 November 2007

i was again at the Ranch today on Ranch business and managed to do some looking around, photographing and filming. it was mostly overcast and occasionally misty. among the better bugs were a dozen or so of thecool Yellow-bordered Flower Buprestid (Acmaeodora flavomarginata) -- the first i've had this year. i had 19 species of butterflies concentrated in one small patch of dying Cowpen Daisy, with the only noteworthy Leps being yet another Peigler's Buckmoth, and my first Ranch and county Great Southern White, although i also had one of those really white forms of the Common/White Checkered-Skipper complex that are always shown in field guides, but that i seldom encounter in the field.

also noteworthy was a nice male Merlin perched in the same snag where i had a first Ranch and County Record Swallow-tailed Kite a few weeks ago. i got some decent, if distant, film of the Merlin.

i refound (besides the now not a late date Pale-faced Clubskimmers) more of the species i documented the other day and added another couple of days via film and photo. i also had another Springwater Dancer (Argia plana), which i could not document that would have added a couple more days.

first, two pair of ovipositing Coppery Dancers (Argia cuprea). i will write up a note on some of this for future publication. i filmed, netted and photographed one pair and released them, since i vouchered the pair sunday.

second, yet another Ivory-striped Sylph (Macrothemis imitans leucozona), a badly chewed up individual that i filmed, netted and photographed, and released. it's worth noting that having searched again on OC i found an old late date record of 13 November 1993 in the UT collection.
