Acronicta menyanthidis

(Esper, 1789) 2286 / 73.042

Morley's Final Catalogue: Two specimens were bred from forced pupae by the Revd. Joseph Greene at the end of March 1857 at Playford near Ipswich (Ent. Weekly Intell. ii, p.11). Suffolk thus becomes an extension of this species' range southwards. I possess one ancient unlocalised example (Mly).

Recent Suffolk Status: Extinct. Unlikely to be found in the county again. A northern species with a small very localized population known from Norfolk the nearest colony to Suffolk.

Life history: Single-brooded.

Identification: Unmistakeable.

Habitat: Moorland, bogs, damp heathland.
