detail

mine

The egg of the first generation is deposited on the wing of a key (sometimes, however, directly on the seed). The larva makes a short, superficial corridor (sometimes only the egg is visible), leading towards the seed, that finally is eaten out. Infested samaras are prematurely shed, and should be sought on the ground. (The larva of the second generation makes a short mine in the bark of a petiole, and from there penetrates a bud that is consumed from the inside out.)
