Review Adaptation-4

I found this caterpillar in my garden. Based on its bright colors, I decided not to pick it up. Why would it be so brightly colored?

  1. To help it hide in flowers.

    No. Its pattern of colors would not blend in with a flower.
  2. To warn away predators.

    Yes! Many brightly colored animals are toxic or dangerous. They use their bright colors to warn potential predators that they taste bad, sting, or have some other characteristic that a predator would want to avoid.

    This is the caterpillar of a Hooded Owlet Moth. They eat the wild asters in our area, which gives them a very bitter taste that birds don't like.

  3. To attract a mate.

    No. Caterpillars do not mate. They must go through metamorphosis into a butterfly or moth before they can mate.
  4. To help it find food.

    No. Most caterpillars eat plants, and bright colors would not help with that..
