Beginners should take care not to confuse this species with Waved Umber. Although wandering individuals might theoretically turn up almost anywhere, the Small Waved Umber is a characteristic species of to calcareous soils of the north of Hertfordshire, positively avoiding the London Clay Basin and the various associated base-poor glacial gravels deposited upon it. The larvae feed on Traveller's Joy Clematis vitalba, including within some larger domestic gardens.
