SEARSPORT — Friends of Sears Island will host a monarch butterfly tagging workshop for adults with Serena Cole on Tuesday, Aug. 23, from 9 to 11 a.m.

Cole will teach program attendees about monarch life cycles, habitat and migration patterns, and will lead a hike to the milkweed field on Sears Island, a certified Monarch Waystation. At the field, participants will have the opportunity to look for butterflies and carefully net and assist with tagging them as part of the Monarch Watch program, which tracks the annual butterfly migration.

Note that seeing and catching monarchs cannot be guaranteed. Space is limited and advance registration is required. To sign up, email Cole at satnam23410@yahoo.com. Registration is complete upon receiving a confirmation email.

Cole has been a biology and environmental educator for 30 years. She has led student science groups to Costa Rica and been involved with citizen science projects at Schoodic Point Educational Research Center.

Registered participants should park along the causeway at the end of Sears Island Road and meet at the island gate. Bring water and a snack and dress for walking through woods and fields, but leave pets at home. In the event of inclement weather, the rain date is Aug. 25 from 9 to 11 a.m.
