Main: (Geometridae / Ennominae)
70.238 [B&F: 1918] Lunar Thorn (Selenia lunularia) (Hübner, [1788])


Local breeding in open woodland and scrub throughout the British Isles, usually in very small numbers; also an occasional immigrant to the south coast of England. In Hampshire and on the Isle of Wight very erratic in appearance, occurring infrequently in mainly coastal locations. Historic records from VC12 North Hampshire have been rejected as unverifiable. Wingspan 39-44 mm. The most likely confusion species is Purple Thorn S. tetralunaria, which see for differences. Larva feeds on Ash, Dog-rose and Blackthorn, over-wintering as a pupa.
