Observations: The pupae were very plentiful in the 1980’s in the stems of reedmace growing on the edge of a flooded disused quarry at Cranford. Although the moths are variable in their ochreous colouration I have never seen the darker form ab. fraterna in the county. Generally the species seems to be seen in small numbers at light.
