Selenia lunularia   Hübner, [1788]

Lunar Thorn

There are only two records from Lewis, the most recent in May 2022. AS the larvae feed on deciduous trees such as oak (Quercus) and birch (Betula)it may have a limited distribution in the islands. It has a distinctive single deep scallop on the hindwing and the white moon-shaped markings on the wing give rise to the common name.
