When applied as directed, the tags do not interfere with flight or otherwise harm the butterflies.Įach fall we distribute more than a quarter of a million tags to thousands of volunteers across North America who tag monarchs as they migrate through their area. These lightweight, circular tags were designed by Monarch Watch specifically for tagging monarchs.

A new series of unique codes is generated for each tagging season and printed using permanent inks on all-weather tags with a pressure-sensitive adhesive backing. In order to be able to associate the geographic "mark" location with that of any subsequent recapture, each butterfly tagged must be uniquely coded. Tagging helps answer questions about the origins of monarchs that reach Mexico, the timing and pace of the migration, mortality during the migration, and changes in geographic distribution. It also shows that the probability of reaching Mexico is related to geographic location, size of the butterfly, and the date (particularly as this relates to the migration window for a given location).
Our long-range tagging program at Monarch Watch continues to reveal much more. Fred Urquhart of the University of Toronto help locate overwintering monarchs and later to determine where monarchs came from that wintered in Mexico. The Monarch Watch Tagging Program is a large-scale community science project that was initiated in 1992 to help understand the dynamics of the monarch's spectacular fall migration through mark and recapture.

All preorders from January 1-July 21 will be shipped beginning in late July to arrive ahead of the migration in your area. The 2022 tagging kits are available via.
