Mine was in captivity since a child, so I don't think it ever developed the skills to fly. But sometimes when I would handle it, it would open and reveal it's eye-spotted wings; maybe because it thought I was a threat, or maybe just to impress me :P. When it was close to dying, it's behavior became erratic and it would fall over and not really be in control of itself. It did clamp onto my finger and take some nibbles in its near death state of confusion, but the spines nor bites could Pierce the skin. I barely felt it.

TL;DR = mine handled fine and possibly enjoyed the excitement of adventuring up my arm. Never any naughty behavior until senility set in.
