Location Accuracy (meters):

Habitat Type:
Woodland/Forest - Trees dominant, and in the over-story
Habitat Type Notes:
They are plentiful in my yard which is very overgrown, 7ft high in the lowest areas, with a small path. The ground is usually damp, as it holds water easily. It's not as many as I saw when I was young, but usually about one per 5 square meter area. They hang out on my wood and concrete porch during daytime until closer to sunset.

Thanks for submitting this firefly observation! It is hard to confirm without a close-up photo of the firefly, but based on the yellow flash color, dusk display time, and low display height, Photinus pyralis is a likely possibility.
