Euura piliserra larvae



3-5(8) larvae in a downwards rolled leaf margin; generally both margins are rolled, in a way that a wide tube is formed. The larva may leave the rolled part of the leaf to feed on the distal, ungalled part, leaving only the veins untouched. The larva lacks a black pigmentation on the last abdominal segments, and also lacks pseudocerci.
