Morley's Final Catalogue: Text for both Chestnut and Dark chestnut: Both abundant throughout the county, the former rather the more prevalent.
Recent Suffolk Status: Common. Still the more common species of the two regularly recorded chestnuts.
Life history: Single-brooded. Regularly recorded on Ivy blossom, Blackberries and Sallow blossom as well as at light. The adults hibernate and emerge again in the spring on mild nights.
Identification: Dark chestnut is often darker in colour and has a pointed wing tip, but this can wear so care is needed when separating the two species. Red-headed chestnut is a much larger species and has 2-3 black marks in the kidney mark.
