A belated thank you for this firefly observation!
Based on the short legs, flat body posture, and indistinct shape of the marking on the pronotum, this is a firefly in the genus Photinus.
Based on the small size and washed-out/grayish coloration, I think it is in the Photinus marginellus/Photinus curtatus complex.
A neat find!
