By Jenna Roller-Knapp Time flies when you’re a mayfly! Mayflies are one of oldest groups of insects, estimated to have evolved between 280-300 million years ago! As such, species in the Ephemeroptera family display many unique morphological differences and life stage strategies.  There are around 4,000 mayfly species globally and an estimated 660 mayfly species in North America (although DNA analysis suggest there may be hundreds more). It takes a skilled eye to identify species (adult or larval phase), trained hand to time the collection specimens, and an adept mind to arrange access to sampling sites. These all pose  challenges for tracking species diversity and changes over time. Interestingly, North Carolina may be a hotspot of mayfly diversity.  The mayfly lifecycle consists of an egg […]
