Scarce merveille du jour moth  (Moma alpium)

Main factors contributing to the decline of this species include the clearance of oak woodlands and inappropriate woodland management, in which mature oaks are not replaced (1).

A Species Action Plan has been produced for this moth under the UK Biodiversity Action Plan (UK BAP). This aims to maintain the range of the Scarce Merveille du Jour. One occupied site is a candidate Special Area for Conservation (SAC), and one is a National Nature Reserve (NNR). A programme of monitoring has been proposed, and conservation action taken for the Light Crimson Underwing (Catocala promissa) and the Dark Crimson Underwing (Catocala sponsa), which inhabit lowland oak woodlands, may benefit the Scarce Merveille du Jour (1).
