The Chrysalis: The caterpillar formed a chrysalis 12.5 days later. (Photo by Greg Kareofelas)
The Adult: The monarch eclosed only 8.5 days after forming the chrysalis and is shown here drying its wings. (Photo by Greg Kareofelas)

Welcome to the world of monarchs, Greta! We don't normally name the monarch butterflies we rear, but we decided that the first one reared from an...
This monarch caterpillar was reared from an egg collected on a tropical milkweed, Asclepias curassavica, in a Vacaville pollinator garden. (Photo by Kathy Keatley Garvey)

After hatching from egg to larva (caterpillar), it eats its shell and then begins munching on milkweed. (Photo by Kathy Keatley Garvey)

When you observe a monarch butterfly laying eggs on your milkweed--and see the predators and parasitoids circling in anticipation--act fast if...
A monarch egg. Soon it will hatch. (Photo by Kathy Keatley Garvey)
This larva or caterpillar has just hatched. Note the black head. (Photo by Kathy Keatley Garvey)
Growing, growing, growing. Now all the caterpillar has to do is eat, eat, eat. (Photo by Kathy Keatley Garvey)
This third instar caterpillar rests on a leaf in its new environment. It was just removed from a lidded container--lidded to keep the milkweed leaf damp. Otherwise, it will dry out. (Photo by Kathy Keatley Garvey)

The monarch butterfly egg is oh-so-very-tiny but what an incredible work of nature! The intricate egg is about the size of a pinhead, 0.9mm wide...

This is the small container that the Garvey family uses to rear monarch eggs. It is about 2 inches wide. (Photo by Kathy Keatley Garvey)
Be aware that if you collect a monarch caterpillar or chrysalis, it may already be parasitized. It is better to start with the egg, says Bohart Museum of Entomology associate Greg Kareofelas. Note the tachinid-infested chrysalis (brown spot). This image, taken in July 2020, shows two chrysalids and three newly eclosed monarchs. (Photo by Kathy Keatley Garvey)
This is part of the Greg Kareofelas setup to rear butterflies. He rears many species. Note the packing foam and chrysalis (not a monarch). (Photo by Greg Kareofelas)
