On Sept. 6, 2016, It Happened

On Sept. 6, 2016, it happened. A monarch fluttered into our pollinator garden in Vacaville and touched down on a Mexican sunflower, Tithonia rotundifola. It wasn't just "any ol' monarch"--if there's ever such a thing as "any ol'...

This monarch, tagged and released in Ashland, Ore., on Aug. 28, 2016, touched down in a Vacaville garden on Sept. 6, 2016. It flew 285 miles in 7 days or about 40.7 miles per day, according to WSU entomologist David James. (Photo by Kathy Keatley Garvey)
