From the look of the above photo it would appear that this butterfly is displaying its dry season form which is supposedly darker than its wet season color.
On its behavior, this butterfly tends to move quite often when feeding on the nutrients from the flowers. This has allowed an excellent 360 degree view of its entire anatomy.
For whatever reasons it may be, this butterfly was seen been chased around by several Ypthima namely 3 rings and 5 rings. I believe it could have been more of a territorial issue rather than a hunter and prey thingy.
Although it is quite a small butterfly at just 2.1cm, it can certainly make a strong impression or should i say "punch" if ever you have the chance to see one.
Butterflies are like Jewels of the Forest and Gardens !
