Ancylis laetana: 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.

Ancylis laetana

(Fabricius, 1775)


Wingspan c. 15 mm

A number of the British Ancylis species are rather similar in appearance, whereas laetana displays an unusually whitish (for the genus) forewing ground colour.

The species is distributed most commonly in the south-east and south of England, but occurs in scattered locations northwards to Scotland.

Flying in May and June in a single generation, the adults appear from dusk onwards and later come to light.

The foodplants are aspen (Populus tremula) and occasionally black poplar (P. nigra).
