Stigmella freyella

Stigmella freyella is a moth of the family Nepticulidae. It is found from the Netherlands to the Baltic region and Russia, southwards to the Mediterranean region. It is also found in North Africa.[1]

The wingspan is 4–5 millimetres (0.16–0.20 in). In Central Europe there are two generations per year.[2]

The larvae feed on Calystegia sepium, Calystegia soldanella, Convolvulus althaeoides, Convolvulus arvensis and Convolvulus elegans. They mine the leaves of their host plant. The mine consists of a full depth, very narrow and often strongly wound corridor. The frass is concentrated in a narrow central line.[3]
