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)
