Watch a monarch caterpillar transform into a chrysalis, emerge as an adult and take its first flight! Monarch caterpillars feed on milkweed and develop through five instars, or growth stages, before forming a ‘J’ shape and transforming into a chrysalis. Observe the butterfly’s wing pattern through the green chrysalis as it darkens just before the adult emerges. After emerging, the butterfly pumps body fluid into its
wings, allowing them to fully expand and harden, before taking its first flight. NARRATOR: During August and September, swarms of monarchs begin their fall migration to warmer, southern lands. On their flights, monarchs often use trees and bushes as overnight roosting sites. During the peak of migration, monarchs cling to the branches of a roost by the thousands. Spring migration usually begins in the last week of February. During their long flight, the monarchs feed on the nectar of spring flowers, and females lay their eggs on milkweed plants. After mating, the female alights momentarily on a milkweed plant and deposits a single egg. In three to five days the larva, or caterpillar, hatches. The larva feeds only on milkweed leaves and grows quickly. As it crawls about, the caterpillar spins from its mouth a sticky thread of silk, which adheres to the plant. The caterpillar holds onto the silk track with the help of small hooks on its prolegs—five pairs of fleshy projections on its abdomen. As it nears full growth, the caterpillar's appetite increases tremendously. It consumes enormous quantities of food in a relatively short period of time. When the larva reaches full development, it stops eating and begins to search for a resting place, where it will change from the larval to the pupal stage. It begins to spin a layer of silk on the surface of the support. Slowly it weaves the silk into a kind of button. The caterpillar then reverses its position and grasps the silk button with its last pair of prolegs. The spines of the prolegs become entangled in the silk mat, and the caterpillar suspends itself in an inverted position, clinging to the silk button. Within 8 to 12 hours, the larva begins to swell. The skin splits just above the head. As the swelling continues, the skin is pushed toward the posterior end of the body. Next, a dark horny barb, called the cremaster, is pulled from inside the larval skin and is pressed firmly into the silk button. The pupa gyrates, and eventually the larval skin drops away. Slowly the pupa case becomes firmer and smoother. Gradually the pupa within takes on a dark green color. Soon, however, the orange and black markings of the adult monarch appear through the transparent pupal skin. Finally, the pupa case splits open. Metamorphosis is complete. The monarch emerges a helpless creature; its soft, limp wings cannot support flight. As it dries in the air, the butterfly pumps body fluid into its wings. With each pumping action, the wings move back and forth. After a few hours the monarch is dry. With wings stiffened by the hardening of the fluid, it is ready for flight. Raising Butterflies BlogEclose Encounters of the Monarch Kind: When a butterfly emerges from the chrysalis! Monarch Metamorphosis: The Final Chapter10-14 days after your monarch forms a chrysalis it will become transparent, revealing the magnificent butterfly inside. Once it’s completely transparent, you know it will emerge that day. The most common question I get at this point is: How can I tell when the butterfly is about to come out? The answer? Go to the bathroom for 5 minutes, and come back to a newly emerged butterfly. 😉 That’s the way it seems to go for many… However, there is a way to indicate that you should hold off on that quick trip to the loo… Look at the top of the chrysalis where the butterfly abdomen is located. When the chrysalis pleats start to expand and separate like an old slinky, the butterfly is about to eclose (emerge) from the chrysalis…or at least within the hour.  Did You Know? If you raise monarchs in cool temperatures or in a dark room, they’ll often hatch later in the day…and days later! Seconds after the butterfly emerges it will look nothing like the majestic monarchs you’ve seen fluttering through your garden. Its wings will be small and crumpled, and its abdomen will be plump and filled with fluids:
A freshly-eclosed butterfly uses mouthparts called labial palps to fuse together the proboscis (straw-like appendage used to take in nectar) from two thin pieces into one super straw. The butterfly will unroll its proboscis and pat it together between the two palps… Over the course of the next minutes, hemolymph from the abdomen will be pumped through the wings, until your butterfly starts looking more monarchesque… About half an hour after a monarch ecloses, it will expel a reddish fluid (through its anal opening) called meconium. This is metabolic waste built up while inside the chrysalis and its expulsion is a normal occurrence to successfully complete metamorphosis.
Potential Issues?Newly emerged butterflies must be able to hang down so their wings can expand and dry properly. If they don’t have room to do this, wrinkled and deformed wings will keep them grounded for life. 😟 If a butterfly falls from its chrysalis and is not immediately placed back up to hang down, its wings will be deformed and it will never fly. If a butterfly is permanently unable to fly (but healthy otherwise) it can be kept as a pet, left outside to support the ecosystem, or euthanized.
If you choose to keep a flightless butterfly, check out this info on feeding adult butterflies. If a butterfly falls from its chrysalis and is too weak to hang on after being placed back up, it is probably heavily infected with OE parasites and should be euthanized to avoid spreading parasites to future generations of monarchs. If a butterfly is unable to emerge from its chrysalis, OE is again the likely issue. If a chrysalis is transparent for more than 72 hours, the butterfly is either deceased or very sick. You can euthanize using the same methods listed above. If your butterfly is able to emerge and dry its wings properly, your final step is on the horizon…safely releasing your butterflies so that they can lay the foundation for future monarch generations.

The process between egg and caterpillar is roughly 18 days. Around day 18 the caterpillar is ready to form a chrysalis.
How do you know when a monarch caterpillar is about to pupate?When the Monarch caterpillar gets ready to pupate it will spin silk, attach itself and hang head-down in a “J” shape. The caterpillar will stay like this for around 24 hours. Shortly before its final molt the caterpillar will straighten some and the antennae will become ragged rather than the normally rigid appearance.
