  1. SOME INSECT SURVIVAL STRATEGIES CAMOUFLAGE EXAMPLE INSECTS: BENEFITS 1. Concealment from predators. 2. Concealment from prey. Praying mantids Walking sticks

  2. SOME INSECT SURVIVAL STRATEGIES continued... WARNING COLORATION click for photo gallery EXAMPLE INSECTS: BENEFITS 1. Easy to recognize from a distance. 2. Warning to predators “Eating me is BAD”! Monarch Butterfly Yellow Jacket

  3. SOME INSECT SURVIVAL STRATEGIES continued... MIMICRY EXAMPLE INSECTS: BENEFITS Predators think you taste bad - even if you don’t. Viceroy - copies monarch Robber fly - copies bumble bee

  4. SOME INSECT SURVIVAL STRATEGIES continued... SOCIAL BEHAVIOR EXAMPLE INSECTS: • BENEFITS • Group defense and care of young. • Specialized jobs: workers, soldiers, etc. • Work together as a “superorganism”. Bees Termites

  5. SOME INSECT SURVIVAL STRATEGIES continued... CHEMICAL WEAPONS EXAMPLE INSECTS: • Types: • Repellants - bad smell or taste. • Cause pain or discomfort - bite/sting Swallowtail Butterfly Larvae, Stinkbugs Bees, Ants

  6. SOME INSECT SURVIVAL STRATEGIES continued... COMMUNICATION Example: honeybees “dance” to tell the location of food sources to others.

  7. SOME INSECT SURVIVAL STRATEGIES continued... COMMUNICATION SOUND Example: male cicadas can sing loud enough to be heard for over half a mile.

  8. SOME INSECT SURVIVAL STRATEGIES continued... COMMUNICATION SMELL=chemicals called “PHEROMONES” Examples: male moths can smell females miles away. Honey bees give off an alarm chemical that other bees can smell.

  9. SOME INSECT SURVIVAL STRATEGIES continued... COMMUNICATION VISUAL Examples: fireflies use flashes of light to attract mates.

  10. Other Examples of Survival Strategies from the Fish World • Misleading Coloration • Coloration can make a fish appear to be something it isn’t • Copperband butterfly fish • Black eyespot near tail is mistaken for an eye by predators • The predator tries to strike the “head” and only gets a mouth full of water or small piece of dorsal fin that the fish can regenerate

  11. Bioluminescence • Lanternfishes emit a bright flash of light from their rear and, at the same time, swim away. • The predator is startled and confused, and focuses its attention on the spot where the flash occurred, giving the lanternfish an opportunity to escape.

  12. Electric eels are capable of generating powerful electric shocks. (up to 600 volts!) • They use their electricity for both hunting and self-defense. • Electricity

  13. Escape act • When a squid is threatened by a predator, he can discharge ink from his anus • This conceals the squid and confuses the predator
