Trifurcula immundella: Distribution map

Please note that the NBN Gateway map service has been terminated as of 1 April 2017.

As soon as a replacement map service is available, distribution maps will hopefully appear here again.

In the meantime, you can get some idea of distribution from the NBN Atlas website.

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.
