Scarce merveille du jour moth  (Moma alpium)

Strongholds exist in Wiltshire, Hampshire and West Sussex. In addition, some colonies occur in East Sussex, Cornwall, Devon and Kent, but it seems that the species has become locally extinct in Suffolk and Essex (1). Elsewhere, this moth has a wide European distribution, and reaches north into Sweden (1).

This moth is mainly associated with mature pedunculate and sessile oak trees (Quercus robur and Q. petraea) in semi-natural ancient woodlands within a range of 80 km of the coast (1).
