The Monarch Butterfly Life Cycle image displays the four stages of the monarch life cycle arranged in a circle. Arrows pointing clockwise (left to right) connect the four stages to demonstrate the progression from one life stage to the next. Text on the image and appearing when you pass your mouse cursor over one of the life cycle stages describes the monarch life cycle's stages and events.

Monarch larvae transform into pupa, also known as a chrysalis. The pupa turns to a jade color with gold markings. The chrysalis becomes clear just prior to emergence.
Image including four pictures of a chrysalis as it matures from an opaque jade color, the chrysalis becoming clearer, until it is transparent with the soon-to-emerge monarch visible inside.
