Apparently some C. spurcus individuals are unsuited to captivity too

The latest one I caught seems pretty afraid of me (it tends to duck to the opposite side of the plant whenever it sees me, whereas some other individuals don't react to suspicious visual stimuli, only vibrations) and keeps trying to fly away and flee its hostplant to the point that it's not eating properly even when I don't come near it, I guess the whole "insects have personalities" thing is true yet again?

I released it because insect personalities are (disturbingly) somewhat heritable apparently habitat fragmentation can make some butterflies evolve to be less explorative and I don't want to raise a batch of specimens that's constantly terrified of me (not to mention the hassle of having to put them back on their plant).
