This moth at a lighted sheet appears to match images of Acrolophus popeanella - Clemens' Grass Tubeworm Moth, and the pattern of this species is supposed to be fairly consistent, according to expert commentary on BugGuide. I see this one pretty frequently at my porch light. Length about 15 mm, wingspan about 30 mm.
Gunpowder Falls State Park Hereford, MarylandBagworms as larva (caterpillars), conceal themselves and feed from a silk case covered with organic material (sticks and leaves). Females never leave this casing. After pupating, males leave the encasement and in the process scrape most of their wing scales off. Males seek out females to mate. The female lays her eggs in her bag. Eggs overwinter and start the process over again.
