Where is it required to obtain a permit or authorization to handle monarchs?

California is the only US state that requires a collecting permit for invertebrates. This includes any type of collection such as using them for scientific research or teaching, or collecting them to rear and release. More information on the California permit can be found here. Monarch Alert provides a blanket permit for their volunteers in California. Information on how to participate in CA tagging efforts can be found here.

In Mexico, it is illegal to touch monarchs, and in Ontario, Canada a permit is required to rear and handle invertebrates (including monarchs). In Nova Scotia, Canada, Monarchs have been listed as endangered, so they and their habitat cannot be touched without a permit.

There may be rules and regulations that we are not aware of that apply in additional states and provinces.
