(Linnaeus, 1758) 162 / 50.001

Morley's Final Catalogue: Larvae are only too frequent everywhere in various trees, mainly willow; imagines much less commonly seen at: Copdock on sugar, Bentley woods at Ipswich lights, Bramford, Playford, Felixstow, Martlesham, bred at Monks Soham in 1905, Fressingfield, twice on sugar at Eye (Tyrer, Ent. Wk. Intell. viii, 1860, 147), on sugar at Beccles; Gorleston. Bury (Norgate); bred at Mildenhall in July 1900.

Recent Suffolk status: Scarce, mainly noted from river valleys. Some records of the distinctive large larvae when they leave inhabited trees to find pupation sites.

Life history: Larva takes 3-4 years to mature. Inhabited trees can show much damage, oozing sap and sawdust with old large emergence holes and smelling 'goaty'. Trees used are often in wet areas. Moth flies in the summer.

Identification: Unmistakeable, a large moth.

Habitats: Wetlands, wet woodlands, river valleys, open woodland.
