Resident, locally rare. Widespread in England, more local in Wales and Eastern Scotland, increasing since 1970.


Unlike any other wave but can be mistaken for a pug moth (e.g. Slender Pug or Maple Pug).  As it is rare a good quality photo is required for a record to be accepted.

Recording method

Adult occasionally found on walls, comes to light including lit windows.

Life cycle

One generation. Overwinters as a larva, during September to May, with pupation in a cocoon on the ground.

Larval foodplants

Larval foodplants poorly known, but possibly plant debris and withered leaves.


Occurs in a variety of grassy, rough habitats including gardens.


The first Dumfries and Galloway record was for Dumfriesshire in 1863 when Lennon had stated is was ‘not common’, but that it occurred on Tinwald Downs, Dumfries (VC72).

The next records came over a hundred years later, for VC74 on 23rd June 1976 at Penninghame House, Newton Stewart and for VC73 on 4th July 1976 at Bridge of Dee, near Castle Douglas (both from Rothamsted moth traps).
