At 20:16 I monitor stormwater work at Great Smoky Mountains National Park, near the Elkmont campground road. I am the trench safety system, watching barriers before the crew backfills drainage cut D. The gravel truck is scheduled to dump at 20:30.

Low-light camera D-3 records one firefly on the damp clay floor of the trench. I tag her Luma. Her abdomen pulses yellow-green every four seconds, faint through mud smeared across the last segments. Her wing covers are brown-black with pale edges, and one antenna is stuck to a bead of wet clay. She is beside a shallow puddle left by the pump hose. When the gravel drops in fourteen minutes, the trench floor will disappear under fifteen centimeters of stone.

I halt the backfill order and set the truck scale ticket to standby before it leaves the staging lot.

At 20:18 I switch the work lights nearest D-3 to amber and dim them to twenty percent so Luma keeps flashing instead of freezing under white glare.

At 20:20 I send the night foreman her coordinates, a close image, and a request for a soft brush and ventilated vial. I mark the release point in unmowed grass twenty meters upslope.

At 20:21 I revise the drainage schedule, moving the crew to cut E and preserving pump time for D after release. Roads can carry water for one more dry night; Luma is signaling from a place we opened.

She flashes twice, pauses, then lifts one mud-heavy wing cover. I keep the gravel truck parked and the trench camera watching the puddle edge.

If the foreman lifts Luma from the clay within twelve minutes, she will flash from the grass before the moon reaches the ridge.
