Sutton & Beaumont, 1989: Widely distributed and often common throughout all five vice-counties, although records of imagines are fewer in some areas probably due to the lateness of the flight season. Larvae are reported to be common on hawthorn in May at Muston (PQW pers. comm.). A useful, but by no means infallible, guide to distinguishing the four Epirrita species from external characteristics is given on page 70 of Dunn and Parrack (1986). This itself is taken from Heslop Harrison (1932). The species can only be separated with certainty by examining the octavals or by larval morphology (AMR pers. comm.).
2012 (CHF): Separation of the four Epirrita species is fraught with difficulty. November Moth is by far the most likely one to be encountered particularly in gardens. The map shows records confirmed by dissection and show that it is widespread across most of the county. Wing markings of well-marked specimens are often very suggestive of November Moth but dissection often shows a different picture so unless dissected they are best logged as "November Moth agg". Page 94 of Waring, Townsend and Lewington (Field Guide to the Moths of GB and Ireland, second edition) shows how the males can be determined.
