Monarch
The monarch butterfly or simply monarch is a milkweed butterfly. It may be the most familiar North American butterfly, and often is considered an iconic pollinator species. These butterflies are capable of distinguishing colors based on their wavelength only, and not based on intensity; this phenomenon is termed "true color vision". This is important for many butterfly behaviors, including seeking nectar for nourishment, choosing a mate, and finding milkweed on which to lay eggs.
