Also the uppersides of the hindwings are black, while the electric-blue area is larger and extended up to the edges. The undersides of the forewings are similar to uppersides but show also a yellow band. The basic colour of the undersides of the hindwings is black, with four pale blue or yellow spots in the middle of a black oval surrounded by concentric yellow bands.

GBIF citizen-science records
It is estimated from how often the Hydaspes Eighty-Eight is recorded against all the insects logged in Iguaçu National Park (268 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.
