Orange Tip - Anthocharis cardamines



Scientific Name: Anthocharis cardamines. The genus name means 'flower grace'. The specific name 'cardamines' refers to one of the host plants, Ladys Smock Cardamine pratensis.

English Name: Orange Tip.

French Name: L'Aurore (='the dawn', or more precisely, presumably, in the sense of 'the rising sun').

  • males have extensively orange tips to their forewings.
  • medium sized (forewings 19 - 24 mm long).
  • undersides of hindwings are marbled yellowy green in both sexes.
  • males spend their time patrolling linear territories such as hedges.
  • upperside of females white with black tips and a dot on each forewing (very like Small White Pieris rapae).
