Elachista quadripunctella (Hübner, 1825)
The larva makes, working from the leaf tip, a large, elongate, lower-surface epidermal blotch. Silk is deposited on the lower epidermis, causing it to contract; the end result is a typical tentiform mine with clear longitudinal folds. The larva then starts feeding on the parenchyma, which changes the initially green colour of the upperside into a mottled light yellow-green. The leaf tip with the upper part of the mine shrivels into a narrow tube, in which the larva deposits its frass. Several such mines are made. Pupation, very unusual for an Elachista, within the mine.
