Lookout for Stragglers in 2014

Filed under: Magicicada,Periodical,Periodical Stragglers — by @ 8:32 am

If you follow Cicada Mania, you’ve probably heard about the regularly scheduled emergences in Louisiana and Mississippi (Brood XXII); in Iowa, Missouri and Illinois (Brood III); and the (micro) brood in Ohio and Kentucky, BUT, there could be other Magicicada emerging around the USA.

Magicicada cicadas often straggle from the times they are expected to emerge. This can happen due to overcrowding (too many cicadas underground can delay the development and emergence of some). It could also be a natural thing they do — maybe some accelerate from a 17 year to 13 year life cycle, or back, to form new populations or as a strategy for survival. Most of the time they straggle in 1 year or 4 year intervals. Here is were I would expect to see stragglers.

  • Brood II 1-year (late) stragglers in CT, GA, MD, NC, NJ, NY, OK, PA, VA
  • Brood IV 1-year (early) stragglers in IA, KS, MO, NE, OK, TX
  • Brood XXIII 1-year (early) stragglers in AR, IL, IN, KY, LA, MO, MS, TN
  • Brood VII 4-year (early) stragglers in NY

If you see any stragglers, report them to Magicicada.org, so they can be mapped and studied. It looks like some Brood IV stragglers are showing up in the Kansas City area!

Of course, we’re only talking about the black & orange & red-eyed Magicicada here…
Magicicada septendecim

…not other species like Tibicen or Okanagana.

  1. I had one emerge yesterday evening and followed it to birdhouse on nearby tree. It appears to be brood xx111 as we live in tn.
