The Caterpillar of this species is grey, smooth, long, and thin, with a flattened head, and has a vague dark line along the back.
The caterpillars have been found feeding on grasses in POACEAE, including
The caterpillars bore downwards and upwards into a leaf of their foodplant creating a translucent white mine between the upper and lowers skins of the leaf. The mine is often along the midrib of the leaf, and filled with water. The frass is accumulated along a line at the side of the mine. The caterpillar grows to a length of about 1 cm.
When mature: the caterpillar exits the mine and forms a pupa in a cocoon composed of a dense silk network, spun at the base of a leaf. The pupa is brown with a narrow dark line along the back, and a vague broader dark line along each side of the back.
The adult moths have brown wings, with three vague dark-edged transverse white bands as well as a vague coppery line along the length of each forewing. The moths have a wingspan of about 8 mms.
The species has been found in
