Trifurcula immundella

(Zeller, 1839)

---

Wingspan 6-8 mm.

One of the palest of our Nepticulids, with a buff ground-colour, slightly darker mottling and yellowish head with white eyecaps.

The larva mines not in leaves, but under the bark of twigs of broom (Sarothamnus scoparia). The mine is visible as a dark gallery, but is easily confused with the similar mine of Leucoptera spartifoliella.

The adult moths are on the wing between June and August, and can be beaten from the foodplant. The species is fairly common throughout much of the British Isles, but probably overlooked.
