Observation
Observation Type:
With Flash Data
Number Observed:
2-10
genus:
photinus
Species:
lineellus
Observation Notes:
Green, multi-pulse flash patterns seen mostly west of the Main Park Road. Flashes were both at the tips of the sawgrass and over head height. Kevin caught an individual doing a double flash pattern with a pulse-period/interval of about 0.4 seconds, but it escaped through a small hole in the net. Based on comparisons with flash behavior of Photinus lineellus and the fact that it escaped through a very small hole, we are relatively confident that this was P. lineellus.
