This species is widespread in Britain, and often attracted to light. Depending on location this species flies from April till October. Very variable in pattern, often indistinguishable from the Small Engrailed (E. crepuscularia). This species is found in woodlands and gardens.
It is often debated whether the Small Engrailed and Engrailed are the same species, and it the future it is possible that they will be grouped together as one species.
