The Brown-winged Root Moth (''Pelochrista medullana'') is a moth of the Tortricidae family. It is native to central Europe, Turkey, southern Russia, Iran and China (Xinjiang).〔(Catalogue of Eucosmini from China (Lepidoptera: Tortricidae) )〕 It has been introduced to Idaho, Montana, Oregon and British Columbia. Introduction in the United States was approved in 1984. The wingspan is 14–21 mm. Adults are on wing from mid June to the end of July. There is one generation per year. Larvae feed on ''Centaurea maculosa'', ''Centaurea biebersteinii'' and ''Centaurea diffusa'' in the rosette stage. They damage the roots of their host, reducing root storage capacity and exposing the plant to pathogens. Small plants are usually completely destroyed. ==References==
