Davey, P., 2009: A migratory species headquartered east of 5°E occurring infrequently in eastern England and rarely elsewhere, the larva feeding on bedstraw (Galium spp.) and willowherb (Epilobium spp.). In Dorset, the moth has been recorded about twenty times from late July until early September. Relatively large influxes of Bedstraw Hawk occurred during 1973 and again in 1995 nationally, and many Camberwell Beauty butterflies accompanied them. A north-easterly airflow is usually established when this species appears, and all twentieth century records backtrack to Scandinavia or countries bordering the Baltic.
