Aspilapteryx tringipennella: exuvium

like is the rule in Gracillariidae, the pupa works itself half out of the mine before the imago emerges.

mine

The mine starts as a long, tortuous, lower-surface (rarely upper-surfce) epidermal, silvery corridor. After a moult the larva works itself to the upper surface of the leaf and begins to make a blotch, soon a tentiform mine, astride the midrib. The mine contracts very strongly, causing the epidermis to develop strong folds, and the leaf to double, almost concealing the mine. Shortly before pupation the larva gnaws a window in the floor of the mine, leaving only the lower epidermis intact, as a preformed exit opening. Pupa in a white fusiform cocoon within the mine. Larvae that have hibernated generally leave their mine, and make a new tentiform mine elsewhere (Emmet ao, 1985a).

hostplants

Plantaginaceae, narrowly monophagous

Plantago lanceolata, maritima.

Triberti (1985a) also mentions P. atrata; however, conceivably this refers to Aspilapteryx spectabilis, a species not yet known at that time.

phenology

Larvae in June – July and, hibernating in the mine, October – April (Emmet ao, 1985a).
