About Stigmella anomalella (Goeze, 1783) Walsingham, 1908
Stigmella anomalella, commonly known as the rose leaf miner, is a moth species in the family Nepticulidae. This species is distributed across all of Europe, extending east into the eastern Palearctic realm. This moth has forewings that are a shining greenish-bronze color, lighter towards the posterior end, with a purple tint on the apical fourth of the wings. The wingspan measures 5 to 6 millimetres (0.20 to 0.24 in). The head ranges from ferruginous-orange to black, the collar is yellow-whitish, the antennal eyecaps are whitish, and the hindwings are grey. Adult moths are active on wing from May to August, and there are two generations produced per year. The larvae of this species feed on the leaves of Potentilla caulescens, multiple Rosa species including Rosa arkansana, Rosa canina, Rosa centifolia, Rosa glauca, Rosa pendulina, Rosa rubiginosa, Rosa rugosa, Rosa tomentosa and Rosa wichurana, as well as Sanguisorba minor and Sanguisorba officinalis. Larvae create mines inside the leaves of their host plants. The mine forms a clear corridor that often has a distinct hairpin turn; the segment before the turn typically follows the leaf margin. The entire first section of the mine is filled with frass. Pupation occurs outside of the leaf mine.
