Pseudoscada erruca is a South-American species of brush-footed butterfly in the Godyridina subtribe of Ithomiini.

[1][3] The type locality of Pseudoscada erruca is Rio Grande do Sul in Brazil.

[4] Research in 2009 on the frequency of occurrence of species in tribe Ithomiini in old-growth tropical forest versus nearby fragmented landscapes[a] found that the presence of P. erruca was more frequent in the latter than the former.

[5] Females deposit individual eggs on the underside of leaves of Sessea brasiliensis and less commonly Cestrum spp., with a preference for plants at a height between 1 and 1.5 m in shaded spots.

[2] Larvae feed from the leaves of the plant on which they hatch, generally developing better on S. brasiliensis than on Cestrum species.
