Fagus sylvatica, Maarn; underside, in more detail

mine

Oviposition at the underside of the leaf, always near a side vein. The mine begins as an elongate blotch of 5-7 mm alongside the vein. This develops into an elongate lower-surface tentiform mine between two side veins, sometimes from midrib to leaf margin. Contraction of the lower epidermis may give the mine a tubular aspect. The lower epidermis has a number of fine folds that are set so close together as to appear one single strong fold. Al frass is heaped in a corner of the mine. The pupa lies in a loose, white, membranaceous cocoon in the opposite corner.

host plants

Fagaceae, monophagous

Fagus crenata, orientalis, sylvatica.

Groenen (1996a) found a mine on Wisteria floribunda; the identification was confirmed by breeding.

Larvae in July and again in late August – late October (Emmet ao, 1985a); hibernation as pupa.
