Acericecis campestre


The larvae of the gall midge Acericecis campestre gall the leaves of various members of the family Sapindaceae which include Maples and Sycamore. A single larva lives in a small depression at the underside of the leaf.  The upper side has a corresponding small bulge, less than 1mm highwhich is surrounded by a pale yellowish circle. After the larva has vacated the gall, a yellow spot remains then eventually withers. The larva is whitish, almost hyaline, short and squat.
