Reddish buff moths are a member of the moth family "Noctuidae". They favour sparse vegetation in open habitat but with surrounding mature scrub or sunny sheltered woodland rides. The presence of the larval food plant, saw-wort is essential.

How to identify

The reddish buff can vary from a worn grey through to a brick pink colour. Wing markings vary also but generally there are two cross lines and dots. Female reddish buffs are smaller than males.


Endangered, only found at Cranmore on the Isle of Wight. Local populations scattered through Europe.

Did you know?

Because the females don't move around very much this species isn't very good at finding new areas to live. The larval food plant is saw-wort.
