Update: in addition, two Brood X stragglers were reported on 5/21 in Bloomington, Indiana (thanks Rhonda and Leah).
Cicada researcher John Cooley has received the first cicada sighting of the year — a Brood XXIII straggler in western Tennessee!! 3 years later than expected.
Just received the first #cicada report of the season… not #BroodVII which is expected, but a 3- year late Brood XXIII cicada from western TN. The cicada season is starting! #uconneeb https://t.co/hIYPH1so8W

So, what’s a straggler? A straggler is a periodical cicada that emerges sooner or later than it is expected to emerge. In this case, a cicada with a 13-year lifecycle emerged in 16 years — 3 years off.
