1.
The Butterfly
When the monarch emerges its wings are soft, flexible and wet. Its heart
pumps fluid from the abdomen to the wings, inflating them to full size.
The wings dry and harden over the next several hours. Release your monarch
outside the day after it emerges.
2.
The Egg
A female monarch identifies a milkweed by "tasting" it with
tiny taste buds on her feet. She curls her abdomen and glues a tiny egg
to the underside of the leaf. A female monarch may deposit several hundred
eggs, usually one egg per plant. The eggs will hatch in three to four
days.
3.
The Larvae
After eating its way out of the egg, the larva will become an "eating
machine", consuming milkweed leaves for approximately 12 days, increasing
its weight almost 3000 times. During this time, the larva will go through
five "instars", which means that they molt (shed their skin)
5 times. When it is molting, the larvae may crawl up the side of the cylinder
and not eat for a while.
4.
The "J" Stage
When the larvae is ready to pupate it will look for a secure place to
attach itself. It will weave a silk mat and button with silk produced
by its lower jaw. The larva grabs the silk button with its rear set of
legs, and forms a "J" before shedding its skin for the last
time. It will hang this way for about a day. The lava will form its chrysalis
relatively soon after its front tentacles hang very limply and its body
straightens out a bit.
5.
and 6. The Chrysalis
The pupa stage lasts 9 - 14 days. The chrysalis will darken the day before
the butterfly emerges and will actually appear to be black on the day
it will emerge. At this point, the wings are visible through the chrysalis.
The butterflies usually emerge in the morning.
