Gelechia sororculella, the dark-striped groundling, is a moth of the Gelechiidae family. It is widely distributed from Europe, throughout Siberia to the Russian Far East. The wingspan is 15–17 mm. Adults are on wing from July to August in one generation per year. The larvae feed on Salix species, including Salix caprea and Salix cinerea. They feed from within spinnings made among the leaves and sometimes in female catkins. Larvae can be found in May. Pupation either takes place within the spinnings or in the ground.
