Thank you for submitting this incidental firefly observation! You found a winter firefly (Photinus corruscus), a non-flashing species that lacks light organs and spends the winter in the adult life stage, which is unusual for fireflies. They are commonly found in the spring, when they fly around looking for mates via chemical pheromones.
*A note about the identification: there are two closely related species, Photinus autumnalis and Photinus lacustris that are also possible, but identification from photos is tricky, and we generally group them with Photinus corruscus. Perhaps in the future we’ll have a better understanding of where each species is found and how to better ID them.
