Florida Monarch Butterfly Populations Have Dropped 80% Since 2005

Florida – November 8, 2018 – From the Florida Museum, “A 37-year survey of monarch populations in North Central Florida shows that caterpillars and butterflies have been declining since 1985 and have dropped by 80 percent since 2005.

This decrease parallels monarchs’ dwindling numbers in their overwintering grounds in Mexico, said study co-author Jaret Daniels, associate curator and program director of the Florida Museum of Natural History’s McGuire Center for Lepidoptera and Biodiversity.

“It’s alarming in a number of different ways,” said Daniels, who is also an associate professor in the University of Florida’s department of entomology and nematology. “This study shows the tight connection between monarchs and milkweed and highlights very dramatic losses in abundance in Florida that further confirm the monarch is declining.””
