Davey, P., 2009: A local species in England, Wales and southern Scotland, the larva feeding on the leaves and flowers of Labiatae plants including thyme (Thymus spp.), wild marjoram (Origanum vulgare), clary (Salvia spp.), mint (Mentha spp.) and common calamint (Clinopodium ascendens). The moth flies in sunshine and occasionally visits light traps. In Dorset, the moth is mainly restricted to unimproved grassland on chalky soil where it is common, very locally.

The following record indicates an additional potential food source: Durlston, adult emerged from bastard toadflax gathered for Epermenia insecurella482 on 26 June 1885 (Reverend E Bankes). A number of records from non-chalky soil sites suggest colonisation of water meadow habitat and gardens, where water mint (Mentha aquatica) and cultivated mint are likely host foodplants, respectively. The peak of the second brood is on average, five times larger than that of the first brood; the first brood emergence appears to very protracted.
