Exaeretia umbraticostella is a moth in the family Depressariidae. It is found in North America, where it has been recorded from South Dakota and British Columbia to Texas and California.[1]
The wingspan is 16–19 mm. The forewings are light reddish ochreous with small diffused blackish-fuscous spots on the costa and around the termen. There is a conspicuous, outwardly diffused blackish-fuscous shade on the middle of the costa, preceded by two minute discal dots of the same colour. There is a light fuscous shade from the costal patch, around the termen to near the middle of the inner margin. The hindwings are shining greyish fuscous.[2]
The larvae feed on Balsamohirza sagittata and Helianthus pumilus.[3] They feed within tubes, formed from tied terminal leaves.
