Number Observed:

genus:

photinus

Species:

macdermotti

Observation Notes:

Species is my best guess, may not be correct. Once again struggled to get good pictures (old phone). Smaller than the Photinus pyralis also present in the same area, measuring in at less than one centimeter. Found over short shrubby ground cover within 2-3 feet of the ground. Surveyed for just a short while, terminated after I caught a few, but flashes had not stopped at that point.
