Brood III or Brood XIX

Filed under: Brood III | Brood XIX — Dan @ 9:10 am

Here’s the old maps (from C.L. Marlatt’s The Periodical Cicada from 1907) for Brood III or Brood XIX. Brood III is a 17-year Magicicada due to emerge in 2014, and Brood XIX is a 13-year Magicicada due to emerge in 2011. It looks like stragglers (periodical cicadas emerging years in advance of when they’re supposed to emerge) in Iowa would be Brood III, and those emerging in Missouri are probably Brood XIX, and possibly Brood III in the north of Missouri. If you find some, take photos, video of their song, etc.

Over the past 100+ years, these maps have been updated, and you can find the updated maps on sites like or Cicada Central.

    Wow, I don’t know how many times I’ve looked at these maps and never noticed there were cicadas in “Indian Territory,” east of OK. Definately needs the update work.
