Ectoedemia rufifrontella (Caradja, 1920)

Lepidoptera, Nepticulidae

mine

Egg generally at the underside of the leaf. The first part of the mine is a corridor that is so strongly contorted as to form a secondary blotch, with much, often interrupted, brown frass. The later part is less strongly contorted; here the frass lies dispered or coiled, leaving a clear margin at either side. The mine often lies close to the leaf margin, and is compacted on a small surface.

hostplants

Fagaceae, monophagous

Quercus pubescens.

Occasionally also on Q. petraea.

phenology

Univoltine; larvae from mid October till November.

distribution within Europe

From Czechia and Slovakia to southern France, Italy, and Greece.

larva

Yellow, head capsule brown; ventral plates present, brown. The living larva has a greenish tinge.

notes

Occupied mines can easily be confused with those of E. quinquella and pubescivora, of which the young larva also has conspicuous ventral plates. However, the larva of rufifrontella has a greenish tinge, and in the first part of the mine the frass is frequently interupted. The mine of pubescivora usually follows the leaf venation (van Nieukerken ao, 2010a).
