Butterflies of Nymphalidae
I have two butterflies here.
They look similar due to the wing designs, but are different. Maybe, we can say they are related as both belong to the same family, Nymphalidae.
The one with white markings on brown is Common sailor butterfly (Neptis hylas). This is a common species seen in Indian subcontinent. Here you can see the butterfly feeding on sandalwood flowers, on a tree behind my house.
Butterfly with orange markings is Common lascar butterfly (Pantoporia hordonia). It’s distribution in India is from the Himalayas to the Western Ghats.
The adults would typically open their wings fully when perching.
This is captured from my backyard.
