Flash Location:
Prolonged flashes occur over vegetation and along creek. Response flashes seen from stationary places in vegetation.
Male Flash Behavior:
Males fly slowly over tops of shrubs, emitting a longer glow-flash of low to medium luminosity, The flash pattern was composed of a single long greenish flash given every ~2 seconds. Interval between flashes varied from 6-9 seconds but more commonly on the lower end of this range.
Female Flash Behavior:
Did not observe clear male-female individual flash communications but did see other fireflies perched on low vegetation (presumably females) that were emitting brief double flashes along the creek.
