Thank you for submitting this incidental firefly observation!
The firefly you observed is Photuris divisa, also known as the Flint Hills firefly or “double flash.” Most Photuris in North America require flash pattern details for a confident species ID, but this species has distinctive coloration that allows for identification with just a photo.
