New discoveries in 2016

The more you know, the more you know how much you don’t know. Huh? There’s always more to discover/learn! My new discoveries in 2016 are presented in reverse-chronological order.

I’m a man on a mission to demystify the art and science of odonate exuviae identification. The task is as challenging as I was led to believe, but with determination and persistence it is do-able.

The specimens featured in this post are the first odonate exuviae that I was able to identify to the species level. Although the specimens were collected in early July, they were identified in early December. New species will be added to my Odonate Exuviae page when their identity is confirmed.


Mulligan Pond at Jackson Miles Abbott Wetland Refuge (JMAWR) is a familiar location where several species, previously unknown to occur at the park, were discovered in 2016.

      Thanks, Mike. “Life-list additions in 2016” (my next post) will tell the rest of the story, as Paul Harvey said famously. You’re welcome to tag along with me next year when I revisit several places where you haven’t gone.
