mine

mine

Oviposition in the underside of a vein, usually the midrib. Here an oviposition scar remains. From this point a small full depth blotch develops, of about one cm in diameter, at the leaf margin, mostly in the leaf tip. The initial part of the mine, a quickly broadening corridor, later often tears in. Frass blackish-green, in short thread fragments, pasted to the upper epidermis. Pupation in the mine, in a globular cocoon, made from secretion that is produced by the larva itself (Scherf, 1964a).
Adult beetles eat linear windows, ± 1 cm long, in the upper surface of the leaf (Gallardo & Cárdena).
