To a human observer these appear as white spots fringed with blue-violet. They actually consist of a white center overlain by bright ultraviolet iridescence, a colour generated by nanostructures on the wing scale surface. Numerous smaller white spots fringe the fore- and hindwings. The ventral surface lacks any ultraviolet iridescence and consists essentially of banded white markings set against a brownish background. These males exhibit lower body mass per unit wing area, implying lower wing loading, more elongate wings, resulting in a higher aspect ratio, which are also the characteristics used to differ them by their conspecific...

GBIF citizen-science records
It is estimated from how often the Great Eggfly is recorded against all the insects logged in Coimbatore (6 verified sightings), 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.
