A butterfly that has significantly increased its range & in numbers here in the U.K. over the past 30 years.
A typical female verso
abb. lanceolata (with pronounced eye spots) female verso
abb. arete (with reduced eyespots) pair verso

A female I reared from ova.
Unnamed abberation.

Here in Thailand we have genus Mycalesis which looks rather similar. Some species have a dry season form with small or vestigial eye spots and large spots similar to the bottom photo above in the wet season form (July-September).

I find arete in the same field in very small numbers each year, all are slightly different but you do have to catch and release hundreds of individuals to find them, it is very time consuming as they hardly ever land and settle for you to look.

A couple more, same field

Have collected Mycalesis in Queensland Australia. Think all my specimens are still papered though. Similar habits to Arphantopus as I recall.
