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]
