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. 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.
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.

With luck
About 10% of wildlife watchers report a Pseudoscada erruca sighting in Iguaçu National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 224th most-seen of the 279 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report a Pseudoscada erruca in Iguaçu National Park on a given day, against under 5% in June–July and September–April, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Pseudoscada erruca sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Iguaçu National Park, in our data
Iguaçu National Park is the only park on Wallace's Line with enough records to rate Pseudoscada erruca sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Pseudoscada erruca is recorded against all the insects logged in Iguaçu National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
