Acrolophus walsinghami

This darling little bagworm moth (whose juveniles and their debris-covered cases are scattered liberally across the sides of my house) is Acrolophus walsinghami. The dark “W” shape on the forewing is “distinctive”, but not definitive — the coloration of the moth is pretty variable, so we’d have to take these poor little things apart in order to 100% determine their species. However, for my given value of “recreational identification”, A. walsinghami is a pretty good guess.

These little guys also suffer from Wikipedia stub syndrome, so other than localizing them to Florida and much of Mexico, I can’t really say much. The caterpillars mature inside an open-ended cocoon decorated with plant debris, which usually are concealed on the trunks of trees, but have a disconcerting tendency to also cover the sides of my house. The adult moths are about 8mm long, nose to tail.
