These programs monitor butterflies in a variety of ways. Some monarch-centric programs involve watching for spring migrants, looking for eggs and caterpillars in the summer months, watching for roosting or migrating monarchs in the fall, capturing and tagging adults, and checking adults for parasites. Other programs collect opportunistic data, structured data via Pollard walks, or other protocols.
