Thanks for this data submission! The insects you photographed were actually moths (looks like grapeleaf skeletonizer moths, not fireflies.
Lots of different insects use a similar color scheme to warn predators of their toxicity, so it can be tricky to differentiate fireflies from look-alikes based just on color patterns.
