Resident, common, widespread. Widespread through mainland Britain. Shows a major long-term decline in abundance.


Use the criteria explained in Waring et al. (2009) and Skinner (2009) to identify the males, but if worn, genitalia examination is necessary. Even this method is useless for females, but rearing from eggs might lead to the males being determined. Only take a minimum of specimens for determination at any one site.

Record undissected specimens as November Moth agg. (Epirrita dilutata agg.).
