A medium-size moth (approx. 2.7 –3.833 cm wingspan). Forewings blue-grey moth with rust and black markings. The basal area and the area in and around the reniform rust brown, area before and lower part of reniform black. Orbicular large, clear blue grey. The claviform spot is a contrasting small black or brown filled wedge.
Very similar to T. rugosa and in particular T. tacoma, but both lack the rust-brown on the forewings found in legitima. There are also differences in the male genitalia.
Adults are nocturnal and come to light, but also fly and nectar during cloudy days. There is a single annual brood.
