Pseudoscada erruca
species of insect
Pseudoscada erruca is a South-American species of brush-footed butterfly in the Godyridina subtribe of Ithomiini. It was described in 1855 by William Chapman Hewitson as Ithomia erruca.
Distribution and habitat
The type locality of Pseudoscada erruca is Rio Grande do Sul in Brazil. It also occurs in other parts of Brazil, such as Pernambuco, and in Argentina.
Pseudoscada erruca occurs in humid habitats with a permanent presence of water. Research in 2009 on the frequency of occurrence of species in tribe Ithomiini in old-growth tropical forest versus nearby fragmented landscapes found that the presence of P. erruca was more frequent in the latter than the former.
Behaviour
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. Larvae feed from the leaves of the plant on which they hatch, generally developing better on S. brasiliensis than on Cestrum species. Adults drink nectar, with a preference for the flowers of Rubus rosaefolius. Adults of P. erruca are on wing in both dry and rainy seasons.
This brief starts where responsible research should: with the source description of “Pseudoscada erruca” as species of insect. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of insect. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Dec 27, 2025. The linked authority identifier is Q3409869. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1855 and 2009.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
