Photinus
Species:
consimilis
Observation Notes:
Flash pattern was very difficult to determine. We didn't document things well enough with our voice notes (but have a plan to do better next time!), and there was a very long pause between each flash of the fireflies (of which we believe there were several species--see the other observation for this survey) so we lost sight of each individual before we could observe a second flash.

This appears to be Photinus consimilis, based on the dark ventrites, dark pygidium, dark scutellum, flared shape of dark pronotal marking, and length of ~10-11 mm. The other Photinus in Florida with similar coloration and size are non-wetland species in the consanguineus complex.
