Stigmella ruficapitella
Stigmella ruficapitella is a moth of the family Nepticulidae. It is found in northern and central Europe. It is mostly absent in the Mediterranean region, with the exception of Mount Olympus in Greece and Trieste. It has recently been recorded from Russia and Bosnia. The wingspan is 4.5–6 mm. The thick erect hairs on the head vertex are black in the male, orange yellow in the female and the collar is black in both sexes Antennal eyecaps are yellow- white. The front wings are dark bronze brown with a weak metallic luster. Hindwings are grey. Adults are on  wing from May to June and from July to August. There are two generations per year. The larvae feed on "Quercus cerris", "Quercus petraea", "Quercus pubescens" and "Quercus robur". They mine the leaves of their host plant. The mine initially consists of a narrow corridor with a thin frass line, soon widening into a fairly long, broad corridor with a largely broad frass line. Mostly, the first part of the mine follows the leaf margin, entering the centre of the leaf after a sharp turn.
