Epinotia immundana: 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.

Epinotia immundana

(Fischer von Röslerstamm, 1839)

Wingspan 12-14 mm.

Generally distributed throughout the British Isles, this species is fairly common in some places. It inhabits woodland, heathland and river banks, where the larvae feed on alder (Alnus glutinosa) and birch (Betula).

The first generation feeds in the catkins, and there is a second generation in mid summer that rolls a leaf longitudinally and feeds within.

The species is quite variable, with the paler diamond-shaped patch on the dorsal area sometimes obscured, yet sometimes contrasting strongly.

The moths fly in spring, from April to June, and in the south, again in August and September.
