Eresia lansdorfi, the false erato or Lansdorf's crescent, is a butterfly of the family Nymphalidae.
Eresia lansdorfi has a wingspan of about 60 millimetres (2.4 in). The upperside of the wings is black. The forewings have a yellowish basal stripe, while the postdiscal area is light red brown, including the costal bar. The hindwings have a pale yellow transverse band. [2]
This medium-sized species imitates (Batesian mimicry) two local subspecies of Heliconius erato (hence the common name) and Heliconius melpomene . [3]
Larvae feed on Ruellia brevifolia . [4]
This species can be found in Brazil, Northern Argentina, Paraguay, Uruguay and Peru. [1]
