According to reports, the Montezuma National Wildlife Refuge has come up with a free monarch butterfly tagging workshop Labor Day weekend. It has been organized at the refuge's visitor's center. Judith Austic is offering the workshop.

It has been set from 2 to 3:30 pm on Saturday on September 5. Austic is a monarch tagging expert and co-owner of a cash crop farm.

People who will attend the workshop will be taught how monarchs are captured and tagged safely. They will also get to know that from where tagging kits could be bought and how data should be recorded and data sheets should be returned.

There is incredible mass migration in monarch butterflies so, each winter, millions of them move toward California and Mexico. According to animals.nationalgeographic.com, only North American monarchs have such a long journey, which is as much as 3,000 miles.

The workshop is organized on the basis of information given by Monarch Watch, which is a non-profit group based at the University of Kansas. The group focuses on educating the public, studying the monarch butterfly and encouraging conservation efforts.

Reports say that those who will attend Austic's workshop will be given an indoor presentation in the visitor's center. After that, they will venture outside with her in order to capture and tag monarch butterflies.

As per reports, each captured butterfly would be 'tagged' with a small dot that will be put on one of its wings and each dot will consist of an identification number on it.
