July 2022

Description

Second Male caught and then released.
Habitat: freshwater interdunal swale, the habitat this species specializes in.
Description: double green flash characteristic of this species. Double flash repeated every 4-6 seconds. Flash is often longer than the pause between flashes, unlike P. fairchildi.
Only other firefly species noted at the site was P. salinus but only 1 individual was found. P salinus gives a yellow flash every second in a series, but this was not observed in any bethaniensis.
Black marking on pronotum widens towards the apical margin but does not reach it, which is apparently unique to bethaniensis. About 10 mm in length. Sternites 1-4 are black, trailing edge of 5 is white and the entirety of 6 and 7 are white. This differs from P fairchildi in that in P fairchildi S4 is almost always partially white.
