Early Thorn Selenia dentaria - 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.

Early Thorn Selenia dentaria

(Fabricius, 1775)

Wingspan 28-40 mm.

Commonly distributed throughout Britain, though less so in Scotland, occurring in a wide range of habitats.

There are two distinct generations (except in the far north), the first of which flies in April and May. The summer brood, which appears in August and September, usually produces smaller and paler moths.

The larvae feed on a variety of deciduous trees.

Melanic forms occur fairly regularly in parts of northern England.
