1918 Selenia lunularia (Lunar Thorn)

Geometridae, Ennominae Wingspan: 32-44mm.

A local species occurring throughout the UK, but confined to established open broadleaf deciduous woodland mostly to the east of Cornwall. Its wing patterns are very similar to the other members of this Genus, but the ground colour is a distinctive pale buff-brown with darker orange-brown markings. As with the others, there are dark wing-tip areas appropriate to their colour shades. At rest this species hold their wings in a partially opened stance which looks quite attractive.

The UK flight season is indicated as May / June with a possible second generation in July / August. In the South. However, in Cornwall, possibly due to under-recording, only small numbers have been seen from April to June.
