Caloptilia cuculipennella

Wingspan c.12 mm.

Although having a fairly wide distribution over much of the British Isles, this is rather a scarce species, and not often encountered.

The larvae initially create a mine on either privet (Ligustrum vulgare) or ash (Fraxinus), and then form two successive cones by rolling a leaf.

Documentation suggests that adults emerge in September, but the Worcester example illustrated was caught in July, perhaps indicating an earlier brood.
