Monarch Rearing

Rearing monarchs can be a fun learning activity for youth and adults, and can provide valuable scientific information if rearing data are collected and reported to citizen science projects, like the Monarch Larva Monitoring Project. However, if you are rearing monarchs in your home or school there are precautions that need to be taken to ensure that you are raising healthy monarchs and not facilitating the spread of diseases or parasites. This page provides resources on how to find and raise monarchs safely. 

We DO NOT recommend purchasing monarchs from commercial butterfly growers to release into the wild. While some breeders may be cautious of disease and test for parasites, many monarch researchers believe that the practice of mass-rearing and selling of monarchs is unlikely to benefit the population, and could actually hurt it. For more information about these concerns, visit Journey North's Raise and Release Safely page.
