The November moth (Epirrita dilutata) is a moth of the family Geometridae. The species can be found in the Palearctic ecozone in Western Europe from Central Scandinavia to the Mediterranean the Caucasus and Western Russia.
The wingspan is 38–44 mm, the forewings being variably marked with alternating pale and dark bands.The forewing ground colour is pale with darker grey and tinted brown. It has wavy lines.The hindwing is white-grey with 2 lines. The distal fascia points in to the discal spot. Melanism is common and in some locations all-dark individuals make up the majority of the population. The species is extremely similar to two of its relatives, the pale November moth and autumnal moth, and they cannot usually be separated without examination of the genitalia. The November moth flies at night from September to November and is attracted to light and sometimes to nectar-rich flowers.
