Anyway, dont know whats going on here. Does anyone else?
Both butterflies look exactly the same on the inner wings. Don't think these are sexually dimorphic butterflies. The one thats flying did this for several minutes, occasionally landed next to the sitting butterfly. The flight was more 'fluttery' than usual. When the flying butterfly landed, it's head was usually pointed at the end of the abdomen of the other butterfly but I couldnt make out what was happening. I guess this is butterfly courtship.
But it didnt end in mating, so I amnt sure. I've heard of territoriality in butterflies, but the sitting butterfly didn't run, so I guess not.
Anyone surer than me?
