The larva bores in the petiole, or even in the bark of a twig. Its activity causes the petiole to swell gall-like. When almost full grown the larve moves through the midrib a short distance into the blade. Here a small blotch is made, from which an oval excision is cut, of c. 2-3 x 4-5 mm. Thus sandwiched it drops to the ground and pupates, awaiting hibernation.
