About Monarchs

Monarchs have an amazing biology and ecology. You can learn more about their migration, life cycle and habitat needs using the pages below. For further monarch biology information visit our partner's webpages: the Monarch Lab, Monarch Watch and Monarch Health.

Monarch Migration

Each year, over the course of a few generations, monarchs make an incredible journey across North America to overwintering sites in Mexico and California.

Life Cycle

From egg to adult, monarchs undergo a fascinating metamorphosis. The life cycle of monarchs is well known and inspirational, making these iconic insects ideal for research and science education.

Habitat Needs

Monarchs rely on specific habitats to shelter and feed their larvae and to provide nectar to fuel adult movement and survival.


The downward trend in the monarch population is due to factors including the loss in abundance and quality of breeding and overwintering habitats.
