We are raising our monarch caterpillars this fall in clear plastic boxes lined with paper towel and milkweed leaves.  A second paper towel is stretched across the top of the box and held in place by the snap-on lid.  The boxes allow the caterpillars to grow without the fear of predators.  Many of the caterpillars we are raising are the third generation descendants of the monarch butterflies raised in May by the previous kindergarten class. 
After eating and shedding their skin four times, the caterpillars hang upside down in "J-form" by a tiny pad of spun silk.  With the final shedding of their outer layer of skin, a lime-green chrysalis speckled with gold dots is revealed.  A monarch chrysalis darkens and wings become visible as the cuticle of the chrysalis suddenly transparent 24 hours before a butterfly will emerge.

When a monarch emerges from the paper-like chrysalis it expands its wings with fluid in its abdomen and still hanging on to its chrysalis, dries its wings for flight.

Kindergartners were very excited to come to discover beautiful orange, black, and white wings where chrysalides previously hung on Monday morning.

The news spread quickly from one kindergartner to the next as the children entered the classroom.  Awe and wonder reflected in the face of every child.  "Wow!"  "They transformed!" "Ah, they are beautiful!"  "Look at them flapping their wings!" was all we could say...
