  1. Mimicry

  2. Batesian Mimicry • Batesian mimicry is a type mimicry where a non-poisonous organism evolves to resemble a poisonous organism. • An example of this would be the resemblance between the Viceroy and the Monarch butterflies • It is necessary for the mimic to maintain its population densities below that of the dangerous species. Why?

  3. Viceroy • The Viceroy butterfly is not distasteful, as its diet as a caterpillar is willow and poplar leaves.

  4. Monarch • The Monarch is distasteful to many species, due to its milkweed diet as a caterpillar.

  5. Müllerian Mimicry • Müllerian mimicry is a type of mimicry where two poisonous organisms evolve to resemble each other. • An example of this would be the resemblance between the Monarch and the Queen Butterfly.

  6. Monarch • The Monarch is distasteful to many species, due to its milkweed diet as a caterpillar.

  7. Queen • The Queen butterfly is distasteful to many species as well, again due to its milkweed diet as a caterpillar.
