two larvae in a communal mine
mine
The mine begins at an egg shell that almost invariably is placed on (not next to) the midrib. The egg is oval, not globular, like in the Nepticulidae. Here a narrow tortuous corridor of some 30 mm begins, with a central frass line, reminding of a Stigmella mine, that often cuts off part of the leaf, causing it to die. Then the larva leaves this mine and begins to make a series of full depth fleck mines (not necessarily on the same leaf). The larva is larger than the mine, and protrudes from it with the rear part of its abdomen. The openings to all these mines are in the lower epidermis. Under the leaf an irregular spinning develops, in which frass grains are trapped. Pupation outside the leaf, in a hammock, like in Lyonetia, but, unlike Lyonetia, not in a cocoon.
