Butterfly populations are a very good indicator of the health of an area's ecosystem !!
Mimic Kite Swallowtail butterflies practice Batesian mimicry, a behavior in which the butterflies' appearance closely resemble that of distasteful species that prevents predation. Swallowtails differ from many animals that practice mimicry.
Non-mimicking butterflies have longer lifespans, if they survive predation, relative to those who mimic.
