Larentia clavaria, the mallow, is a moth of the family Geometridae. The species was first described by Adrian Hardy Haworth in 1809. It is found from Siberia (Altai Mountains) in the east to the Iberian Peninsula, North Africa, and the British Isles in the west. In the north it ranges to the Caucasus, Tajikistan and Fennoscandia. In the south it is found the western Mediterranean islands, Italy, the Balkans and Asia Minor. It occurs only locally and is almost always rare. In the Alps, it rises up to 1200 m above sea level.
