Cicada Mania

B is for Brood. Here’s the basics:

Magicicada cicadas are American periodical cicadas that have 17 or 13 year life cycles. There are 12 groups of Magicicadas with 17 year life cycles, and 3 groups of Magicicadas with 13 year life cycles. Each of these groups emerge in a specific series of years, rarely overlapping (17 year groups co-emerge every 289 years). Each of these groups emerge in the same geographic area their parents emerged. These groups, each assigned a specific Roman numeral, are called broods.

Two examples:

Brood X (X is the Roman numeral for 10), emerges every 17 years, in DE, GA, IL, IN, KY, MD, MI, NC, NJ, NY, OH, PA, TN, VA, & WV. The last time Brood X emerged was in 2004, and it will emerge again in 2021.

Brood XIX (19) emerges every 13 years, in AL, AR, GA, IN, IL, KY, LA, MO, MS, NC, OK, SC, TN, VA. The last time Brood XIX emerged was 1998, and it will emerge next in 2011 (NEXT YEAR)!

When is the next Brood emerging in your area? Consult the Brood Chart.

I’ve only scraped the surface about the who, why, when, where and how of Broods. If you want to learn more I highly recommend Gene Kritsky’s book Periodical Cicadas: The Plague and the Puzzle. There are also online resources such as Cicadas @ UCONN (formerly Magicicada.org), which has updated brood maps, and Cicada Central.

A is for antennae. Cicadae antennae are situated between their eyes and their clypeus. Insects use their antennae to smell and sense touch, temperature, and vibration.
