Dragonflies are one of summer's most interesting insects. I don't know much about them and I was surprised to see the number of different dragonfly species in Michigan. I thought I'd do a quick internet ID on this one, but quickly got lost. Even the beginner's guide to Dragonfly ID was intimidating.
I teach economics at Kalamazoo College. My wife is also an economist. We were on sabbatical in Europe for the 2014-15 academic year. (Salamanca, Spain, followed by Oxford, UK.) We were in Uruguay for the 2006-7 academic year.
