Approximately 300 Monarch butterflies were tagged and released by guests at the Norfolk Botanical Garden on Sunday.
The event was included in the admission for the day. Guests got a brief training session before being able to participate in the tagging of the butterflies.
A certificate was given to the guests who joined in.
The Norfolk Botanical Garden says thousands of Monarch butterflies leave the U.S. and migrate to Mexico. The peak season for their migration is between Sept. 18 and Sept. 26.
Monarch butterflies can travel up to 100 miles per day during migration.
The event was in partnership with the Butterfly Society of Virginia.
