T-Marking Moth / Giant plume moth species

Gardens, meadows, and semi-wooded areas; often found indoors resting on walls near light sources.

Larvae feed on various plants, notably bindweed (Convolvulus) and morning glory; adults feed on nectar.

Distinctive T-shaped resting posture with narrow, rolled-up wings held at right angles to the body. They are primarily nocturnal and highly attracted to artificial lights.

Harmless to humans; no sting or bite. Can be considered a minor garden pest if larvae are numerous, but generally provides ecological benefit as part of the food chain and incidental pollination.
