exuvium

mine

Egg elongate, with strong longitudinal ridges, at the underside of the leaf, in the basal part, near the midrib. The egg is partly inserted into the leaf tissue. The mine begins as a long, narrow, full depth gallery running towards the leaf tip; frass here in a narrow central line. After the leaf tip has been reached a large, full depth, brown blotch is made. Much silk is deposited within, strongly contracting the mine and making it opaque. Frass lies in big black lumps here either in the oldest part, or in the centre, of the blotch. The larvae are capable of leaving their mine and restarting elsewhere, in which case the initial corridor is missing. Larvae of the first generation hibernate in the mine. Pupation external, in a white spinning, often between the leaves of the hostplant.
