Morley's Final Catalogue: Distinctly scarce, and known from only Bentley, Brandeston, Needham, Stowmarket, Bury, Ickworth; and Beccles. Henham in August 1924 (Mr).

Recent Suffolk Status: Suffered a massive decline nationally in the 1970s following the outbreak of Dutch Elm disease. Last record in the county at that time was in 1968. Thought to be extinct. Unexpectedly reappeared in 2021 in the west of the county, with more records from 2022 onwards suggesting the species may be attempting to recolonise the county from Cambridgeshire where it has been increasing. Confirmed as a breeding species in Suffolk in 2026, with larvae found at Lackford.

Life history: Single-brooded. Larvae feed on epicormic growth on Elm trees.

Identification: The large white patches along the costa should separate this species from the other pinions.

Habitat: Hedgerows with Elms, woodland.

Verification Grade Comment: Very rare.
