Junonia hedonia is a butterfly that was initially thought to exist in south Johor and Singapore, as mentioned in C&P4 1992.
Even before that it seem to have enter the Klang Valley & gradually become the dominant species replacing J. iphita.
In P. Malaysia J. iphita is found in open ,wastelands & scrub around villages.
In the Klang valley J. hedonia becomes common in roadside waste grounds & forest edges.
J. hedonia have now spread across KL to pahang & the east coasts to S. Thailand.
Curiously it does not seem to have spread much north of Selangor.
The two can be confusing in fieldshots, & possibly there is some degree of intermediates.
The important features for ID are.
Junonia iphita.
Dull ochreous brown
1. UpH ocelli smaller ,dull brown & laid on a diffuse dark fascia.(ID certainty.)
2. UnH discal dark fascia with a thin dark-eged pale band lining its inner border.
Ocelli weakly contrasted.

Junonia hedonia ida.
More reddish brown.
1 UpH ocelli large, often orangey on a clear ground. (ID certainty.)
2. UnH dark discal fascia not edged by a pale thin band on its inner border.(some example weak)
3. UnH ocelli better defined ,often orangey.

Two observations from Perak State IDed as J. hedonia are doubtful. They both have a pale line/band on the inner margin of the UnH dark fascia and are likely to be J. iphita.

There seem no other records from Perak or further north of it in P. Malaysia.
