  Insects on High

  After an exhaustive search for the creepy crawlies living in a small patch of Panama's rain forest, researchers have discovered that the entire 6,000-hectare forest could harbor up to 25,000 arthropod species.

  Dawn Frame and Alexey Tishechkin, researchers with Project IBISCA-Panama—supported by the Smithsonian Tropical Research Institute—stand in a crane gondola so that they can capture insects feeding on flowers in the forest canopy.

  Open “Eyes”

  An Io moth—known for the false "eyes" located on its hind wings—is one of the many species identified by scientists during a project spanning nearly a decade.

  Ant Mimic

  A broad-headed Hyalymenus nymph (right), mimics its ant neighbors (left) while visiting a flower. By looking like an aggressive ant that can sting attackers, the harmless nymph tricks predators into leaving it alone. Mimicry is a type of camouflage and occurs throughout the animal kingdom. ("Art of Deception": Can you find the animals hidden in these photos?)

  Foggy With a Chance of Bugs

  Researcher Jürgen Schmidl fogs the rain forest understory in an attempt to collect insects in the vegetation. Some techniques use chemicals that stun the insects, causing them to rain down on sheets laid out to catch them.

  Deceptive Defense

  Normally, saw-nosed plant hoppers try to keep a low profile. Blending in with tree bark offers some protection from predators. But when their cover is blown, plant hoppers have a second line of defense: Flashing the red spots hidden under their wings gives the impression that the eyes of a much larger animal are staring back.

  Although some beetles are famous for their metallic jewel tones, this scarab beetle (Megasoma elephas), also known as an elephant beetle, is covered in brownish yellow hairs. This scarab beetle species flaunts itself in other ways—males sport a horn that they use in fights with other males for mating rights.

  Red Flags

  A flat-footed bug uses flashy red "flags" on its hind limbs to distract potential predators, such as birds. By placing attractive lures away from vital areas such as the head, the insect ensures a striking predator will miss the important bits.
