Angled Castor is a common butterfly found all over the island in all the year round, though becoming scarce above 1200m. It is abundant in degraded vegetations. Its larval host plant is Thel Edaru (Ricinus communis), a plant which is widely cultivated to extract Castor oil. Hence the vernacular English name for this butterfly. However in Sri Lanka only three Tragia (කහඹිලියා) species are identified as its larval host plants (Tragia plukenetii, Tragia involucrata(Indian Stinging Nettle) - both Known as වැල් කහඹිලියා in Sinhala and Tragia hispida)
