Rose Leaf Miner Stigmella anomalella
Wingspan 5-6 mm.
A fairly common species throughout the British Isles.
The larva mines the leaves of rose (Rosa spp.), both cultivated and wild varieties. The mine is a long, sinuous gallery which often crosses back over itself. The frass is initially green and cloudy, filling the mine, but later is a thick black central line.
The adult moths have plain bronzy wings, tinged greenish on the inner two-thirds, and slightly reddish towards the tip.
There are two generations, with moths flying in May and August, the larval mines occurring in July and from October to November.
