Butterfly and Dragonfly Populations, what Research shows

Doug Taron, Curator of Biology and Vice President of Research and Conservation, Peggy Notebaert Nature Museum

“I don’t see as many butterflies as I used to.” Is this statement really true?

Doug Taron from the Illinois Butterfly Monitoring Network tracks long-term trends in butterfly populations.  He sees a significant decline in abundance from 1997 to 2017 both regionally and in individual counties.  He will discuss his research, which also includes dragonflies and damselflies, as measured by the Illinois Odonate Survey.
