The larva lives as a bark miner and stem borer in late summer and autumn. It descends into the rootstock for hibernation. After hibernation large, lower surface blotch mines are made in the lower leaves, from a gallery in the bark. They start in the base of the leaf, and are centered over the midrib. The mine contains hardly any frass. The larva can make several mines. Sometimes several larvae in a mine. Pupation in the mine.
Onagraceae, narrowly monophagous
Maček (1999a) also mentions Chamerion angustifolium; this needs further confirmation.
Mining larvae in early spring, up to April.
