Photuris versicolor (Fabricius)
Orig. Comb: Lampyris versicolor Fabricius 1798
The useful characters of the original description are: large size; black antennae with the articles a little pale at base; black elytra with margin, suture, and a short vitta yellow; black legs with knees yellow. (2)
(but note that Barber (1951) isn't fully reliable) (3)
Flicker of 3-4 (rarely 5-6) rapid flashes, (often seen as a jagged flicker at warm temperatures, but as separate flashes below ca 65° F); flashes with decreasing intensity, but especially or only noticeable on last flash of pattern; repeated at 3-7 sec interval (4)
Of the 19 spp. and varieties covered by Barber's (1951) key all but five are in the versicolor
group, distinguished by a pronotal marking consisting of a median longitudinal black vitta of varying outline with a red or orange spot on each side of it; the differences in extent and form of the black vitta are of diagnostic value when considered in connection with other group. (5)
