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. 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. 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.
