Each year, millions of monarch butterflies undertake their annual fall flight to Mexico. Nets and tags will be available during the event for those who want to capture and tag monarch butterflies.  Participants head out into the flower-filled fields and shelter belt around KWEC to capture monarchs, with tagging leaders stationed along the trail to help with the tagging process.  For the past several years, monarchs tagged at the event were recovered at three Mexico roost sites.
