Biologist Collecting Insects at Chihuahua Marsh Twilight

Pale winter light falls through clear air over a dry marsh edge near Chihuahua, casting long shadows across the dormant reeds. A biologist stands in profile, holding a fine net poised above the grasses, while several beige specimen envelopes rest on a nearby metal tray. Laboratory instruments on a portable table nearby show faint indicator lights as they warm up for the evening. The researcher wears a heavy wool coat and leather gloves, their posture rigid with concentration. Frost crystals glint on the dry stalks in the foreground, against the darkening blue sky above the horizon line. One envelope flap catches the last light, revealing a tiny insect wing inside.
