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. 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. Wikipedia →

Rare
Under 5% of wildlife watchers report a Coyote Brush Stem Gall Moth sighting in San Francisco on a given day, based on 109 verified sightings from GBIF citizen-science data. It is the 150th most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Coyote Brush Stem Gall Moth is recorded against all the insects logged in San Francisco (109 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
