Eucosma wimmerana is a species of moth of the Tortricidae family. It is found in China (Tianjin, Hebei, Henan, Shaanxi, Gansu, Xinjiang), Mongolia, Japan, Russia, Kazakhstan[2] and Europe, where it has been recorded from Sicily, France, the Netherlands, Austria, Switzerland, Italy, the Czech Republic, Slovakia, Poland, the Baltic region, Slovenia and Romania.[3]

The wingspan is 14–17 mm. Adults are on wing from June to July.[4]

The larvae feed on Artemisia campestris and Artemisia dracunculus. Larval feeding results in gall formation. The gall has the form of a swelling of the apical part of the main shoot. The larvae have a yellowish or reddish body and blackish brown head. Pupation takes place within the gall or in the soil.[5] Larvae can be found from September to May.
