Similar species:

Forewing: 4.5 to 5.5mm

Habitats: Mountain moorland and glens.

Habits: The moth flies above the foodplant on sunny afternoons.

Foodplant: In the autumn the larva forms a transverse mine across a leaf of Bearberry, causing one side to stay green, the other variegated (red, brown, black). In the spring it spins a young shoot and feeds on the surface of the leaves causing inflated mines containing frass. It pupates in one of the inflated mines.
