This observation originally lumped voucher specimens 7, 8, 9, and 10. While all the specimens were Photuris, these included both sexes and they varied in their hind coxae coloration, so I separated them into individual observations.
This particular firefly is a female Photuris. The dark hind coxae and habitat suggest Photuris tremulans, but more precise flash pattern details would be needed for ID.
