Caloptilia rufipennella (Hübner, 1796)
small red slender

Acer saccharinum, Amsterdam

initial mine; the iridescent patch at right is the empty egg shell
mine
The mine begins as an inconspicuous, lower-surface, epidermal corridor. This widens into a smallish triangular blotch, usually in the axil of a vein; the mine is fairly transparant, and is about 6 mm in length. Older larvae live free, in in a lobe of the leaf that has been forced downwards and rolled into a cone. In the course of its development the larva makes three (rarely two) of such cones, ascending in size, on the same leaf or not; the first is no more than a downfolded leaf margin. Pupation in a membranaceous, yellowish cocoon at the underside of a leaf.
