Davey, P., 2009: A widespread species in Britain, the larva is polyphagous and occasionally a pest in market gardens to tomato plants (Lycopersicon esculentum). In Dorset, the moth is ubiquitous and common. "In those parts of the country I know, sufficiently abundant to be a pest. Its larvae are especially destructive to gladiolus flower spikes, lupins, carnations and primulae." (W Parkinson Curtis ms). The moth appears to have two brood cycles, a single brood in July, and a double brood peaking in June and again in September. Examples are observed as early as April 1 and as late as November 4.
