mine

Milky white upper-surface primary blotch, sometimes with an orange hue; no trace of a preceding corridor. The inside is lined with much silk, but the mine remains completely flat. The larva soon starts making of a discoid cocoon, about in the centre of the mine. When not feeding it rests in a horshoe-like posture in its cocoon. The mine contains practically no frass, which is ejected through a cut in the upper epidermis near the margin of the mine. Pupation within the mine.

hostplants

Fagaceae, oligophagous

Castanea mollissima, sativa; Quercus cerris, dalechampii, faginea, x hispanica, frainetteo, ithaburensis subsp. macrolepis, macranthera, macrocarpa, petraea, pubescens, robur & subsp. pedunculiflora, rubra, serrata.

A communication by Descka (1983a) that the species were bred from the evergreen oak Q. trojana is probably erroneous.

phenology

Larvae from July. The autumn larvae hibernate in the mine, in the fallen leaf; they pupate only in the spring (Emmet, 1983a).

notes

Hering (1957a) writes that normally larvae occur from September on. This no longer is the case; mines can be found in number already in early-July.

Emmet (1983b), van Frankenhuyzen & Freriks (1979a) and Jordan (1995a) present details of the biology.
