Apatetris elymicola

Apatetris elymicola is a moth of the Gelechiidae family. It was described by Sakamaki in 2000. It is found in Japan (Hokkaidô).

The wingspan is 10.1-11.4 mm. The forewings are pale grey, irrorated with fuscous, becoming darker towards apex and with two stigmata on the plica, one at the plical half and the other at three-fourths. The hindwings are fuscous.

The larvae feed on Elymus mollis. They mine the leaves of their host plant. Three to five larvae may mine a single leaf blade. Mature larvae overwinter in the mine. Pupation takes place in a dead leaf.
