Morley's Final Catalogue: This beautiful noctuid, still common in the New Forest, cannot have become totally extirpated from 'near Ipswich' (Harwood and Garrett, circa 1870), 'Ipswich' (Long, Entom. 1875, 200), 'Bentley and Holbrook' (Garrett and Tim Last). Insufficient cause emerges.

Recent Suffolk status: Like the Dark Crimson Underwing there were no twentieth century records from the county.

As a presumed rare immigrant, we have five recent records of this catocalid, which is far rarer as an immigrant than sponsa; from Minsmere on the night of 22.07.2017 (C. Moore), Hollesley on 17.07.2018 (R. Watson), Butley on 02.07.2020 (H. McClennon-Warnock), Purdis Farm, Ipswich on 21.07.2023 (N. Sherman) and Homersfield on 27.07.2023 (M. Timms).
Quite possible that this species may recolonise the county as it appears to have re-established in Kent in recent years.

Life history: Single-brooded in one long extended generation. Appears slightly earlier in the summer than Dark Crimson underwing.

Identification: Compare with Dark Crimson Underwing and Minsmere Crimson underwing. Dark Crimson underwing has a very wavy dark band on the hindwing.

Habitat: Woodland.
