Identification: The moth is similar to Bucculatrix ulmella but the ground colour is white to buff with a white to buff head tuft. The markings lack the terminal dark dash of B. albedinella which is whiter still. More Info 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.
