The Caterpillar of this species is greenish-grey, smooth, long, and thin, with a flattened pointed head. The caterpillar has a vague pale line along the back, accompanied by a vague dark line along each side.
The caterpillars have been found feeding on
The caterpillars bore downwards into a leaf of their foodplant creating a translucent white mine between the upper and lowers skins of the leaf. The mine is initially narrow, and broadens as the caterpillar matures. The mine reaches the whole width of the leaf, and a length of up to 20 cms. The frass is packed at the top of the mine. The caterpillar grows to a length of about 1 cm.
When mature: the caterpillar exits the mine and forms a naked pupa, usually facing head downwards, attached to the midrib of a leaf by a silk girdle and some hooks on the underside of the pupa.
The adult moths have speckled brown wings, with two vague pale areas near the middle of each forewing. The females sometimes have a white spot near the tip of each forewing. The moths have a wingspan of about 8 mms.
