Gnorimoschema octomaculella is a moth in the family Gelechiidae. It was described by Vactor Tousey Chambers in 1875. It is found in North America, where it has been recorded from California and Washington.[1] [2]
The forewings have a brown spot on the dorsal margin near the base, which is brownish, and also a large rust-red spot on the disc before the middle which touches a brown costal spot placed just before it. There is another rusty-red spot at the end of the disc, and a rather dense small patch of dusting before the costal cilia, and one also before the dorsal cilia. The hindwings are pale grayish fuscus.[3]
The larvae feed on Acamptopappus sphaerocephalus.
