Gnorimoschema baccharisella

Description

Gnorimoschema baccharisella is a moth in the family Gelechiidae. It was described by August Busck in 1903. It is found in North America, where it has been recorded from California. The length of the forewings is 6.2–8.5 mm for males and 6.5–9 mm for females. The forewing pattern consists of a pale peach-colored basal patch which is variably tinged with rust, the remainder of the wing is pale to dark grey. There is also a subtle, longitudinal streak of rust on the fold in the cell and there are usually two additional rust spots in the middle and at the end of the cell. Adults are on wing from mid-July to late November. The larvae feed on Baccharis pilularis, causing hard stem galls. Pupation takes place on the ground.
