The egg is laid on the underside of a leaf usually in a vein axil. The early instar larvae create a contorted gallery leading to a straight section usually alongside a vein. The mine is filled with black frass. The larvae emerge from the underside of the leaf where they feed windows from the leaf. There are commonly more than one on a leaf. They pupate in a dark ribbed cocoon on the underside of the leaf. The pupal stage passes the winter.
