Stigmella regiella

Stigmella regiella is a moth of the Nepticulidae family. It is found in most of Europe (except Iceland, Ireland, Portugal, Norway, Finland, the Baltic region and the southern part of the Balkan Peninsula), east to the eastern part of the Palearctic ecozone.

The wingspan is 4.5–5 mm.

The larvae feed on Crataegus laevigata, Crataegus monogyna and Mespilus germanica. They mine the leaves of their host plant. The mine begins as a corridor that usually follows the leaf margin. After a moult, an elongated blotch is found, generally the direction of this blotch is opposite to that of the corridor.
