Callisto insperatella (Nickerl, 1864)

Lepidoptera, Gracillariidae

mine

Oviposition at the underside of the leaf, generally near a lateral vein. The mine begins as an epidermal gallery with a central frass line. The gallery widens to a blotch, and the larva starts consuming the parenchyma. In the end a lower-surface tentiform mine is the result, strongly contracted, but without folds. The larva vacates the mine by an opening in the lower epidermis, then lives free in a leaf margin that has been folded downwards.In the fold the larva starts feeding in the apical (directed to the leaf tip) section, working downwards. The frass is accumulated in the oldest part of the fold. During feeding pauses the larva rests in the green, still untouched, part of the fold. After the first fold has been eaten out a second one is made.
