Owl Butterfly
A very large tropical butterfly with enormous owl-eye patterns on the underside of its hindwings. The uppersides are deep blue-purple.
Did You Know?
The large eyespots on its underwings closely resemble the face of a screech owl which startles would-be predators.
Common Tree Nymph
A very large butterfly with translucent white wings heavily veined and spotted in black. It flies with a slow, lazy, paper-kite fluttering motion through the forest understory.
Did You Know?
Its slow, floating flight advertises its toxicity to predators - the caterpillars store alkaloids from their host plants that persist into adulthood.
