Location and Habitat
Location Accuracy (meters):
0-25
Habitat Type:
Developed - Sub/urban areas; parks/gardens
Habitat Type Notes:
We are an older city neighborhood of homes built in the 1950s. The lots are between 1/3 and 3/4 acre for the most part, the homes are mostly between 2500 and 3500 square feet, and nearly all of them have large mature trees, generous landscaping and grass lawns. The trees are mostly live oak, pecan, crape myrtle, mesquite, and ash. There is a nearby park of about 6 acres that is mostly grass and mesquite trees.

Artificial Light Notes:
Our street is pretty dark - we don't have any streetlights and it's a quiet street with few cars and little traffic. Most of the houses, including the one where we saw the fireflies, turn their porch lights on at dusk and keep them on all night.

Observation Notes:
I didn't approach the fireflies as I didn't want to scare them away. I saw about 3 of them flying around above the grass and near the landscaping shrubs and bushes, and I saw two huddled together on a blade of grass that did not fly. The ones in down in the grass were just glowing and not flashing, but the ones that flew around were turning on and off.
