The length of the forewings is 2.5–3 mm for males and 2.7-3.2 mm for females. The forewings are dark BLUE-brownish with silver-whitish Hats. There are probably multiple generations per year.[2]
The larvae feed on Eccoilopus cotulifer and possibly Spodiopogon sibiricus. They mine the leaves of their host plant. The mine has the form of a full-depth and linear gallery, extending almost straight towards the leaf-apex. Pupation takes place outside of the mine. The species probably overwinters in the pupal stage.[3]
