Swallowtail Butterfly
Elegant butterfly with yellow wings marked with black veins and blue-red eyespots on hindwings. The tail extensions on hindwings divert predator attacks from the body.
Did You Know?
Swallowtail caterpillars have a hidden orange forked organ called an osmeterium that they pop out from behind their head when threatened, releasing a foul smell.
Giant Robber Fly
A large, bristly predatory fly with powerful grasping legs and a sharp proboscis. It ambushes prey in mid-air with remarkable speed and precision, including insects larger than itself.
Did You Know?
Robber flies inject prey with saliva containing neurotoxins and digestive enzymes, liquefying the insides and then sucking them out.
