A Brood V straggler found by Matt Berger in West Virginia. See more photos of this cicada.
The emergence of Brood XXIII is well underway in the states along the Mississippi, and Brood IV should kick off in the west as soon as it stops raining every day. These aren’t the only Magicicada periodical cicadas emerging in the U.S. this year — some stragglers will emerge as well.
A straggler is a periodical cicada that emerges before or after the rest of its brood. Typically a straggler belonging to a 17 year brood will emerge 4 years early, but they might also emerge a year early, or a year late, or even 4 years late. This probability chart, details the probability of a straggler emergence.
In 2015 you might find the following stragglers:
- Brood XIII 17 year cicadas emerging 4 years early in OH, PA, WVA.
- Brood V 17 year cicadas emerging 1 year early in NY, OH, PA, VA, WVA.
- Brood XIX 13 year periodical cicadas emerging 4 years late in AL, AR, GA, IL, IN, KS, KY, LA, MO, MS, NC, OK, SC, TN, VA
- Brood XXII 13 year cicadas emerging a year late in LA, MS, OH, KY
