    Pupa (Chrysalis)   Imago (Adult)
    ?   Mimics as an unpalatable poisonous species, avoided both by birds and lizards. It also has tough, leathery skin to survive such occasional attacks. When attacked it fakes death and oozes nauseating liquid which makes it smell and taste terrible. It recovers soon after the attack.
