Mycalesis perseus, the dingy bushbrown or common bushbrown, is a species of satyrine butterfly found in south Asia and southeast Asia. Mycalesis perseus exhibits seasonal dimorphism with distinct wet-season and dry-season forms.
Wet-season form. Male and female. Upperside dark to somewhat pale vandyke-brown. Fore wing with a white-centred, fulvous-ringed, black ocellus in interspace 2, and rarely a very small but similar ocellus in interspace 5. Hind wing uniform, occasionally two or three postmedian obscure ocelli present. Fore and hind wings with subterminal and terminal pale lines. Underside: the groundcolour, subterminal and terminal lines on the wings as on upper-side, but crossed by a common purplish - white narrow discal fascia. Fore wing with from two to four, hind wing normally with seven ocelli, similar to, but more clearly defined than, the ocelli on the upperside; on both wings the line of ocelli bordered inwardly and outwardly by sinuous purplish-white lines. On the hind wing only the three posterior ocelli in a straight line, the rest strongly curved outwards. In the female the median or posterior ocellus on the upperside of the fore wing is always larger... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Dingy Bushbrown is recorded against all the insects logged in Yogyakarta (8 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.
