Periodical cicadas (“locusts”) Brood XIX (19) will emerge in 2024 in Fifteen States

Filed under: Brood XIX | Magicicada | Periodical — Dan @ 1:01 am

April 11th: Magicicada cicadas have begun to emerge. Little by little and before you know it the full emergences will begin. Special note: Brood XIII will also emerge in 2024. While the two broods do not overlap, they come closest in the Springfield, Illinois area.

Periodical cicada Brood XIX (19) will emerge in the spring of 2024 in Alabama, Arkansas, Georgia, Illinois, Indiana, Kentucky, Louisiana, Missouri, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, and Virginia. The last time Brood XIX emerged was in 2011.

What, when, where, and why:

What:

Millions of these cicadas:
Adult, Nymph, Molting Cicada

  • Cicada insects with a 13-year life cycle.
  • Some people call them “locusts” but they are really cicadas. (Locusts are grasshoppers.)
  • Which species: All four 13-year species:
    • Magicicada neotredecim Marshall and Cooley, 2000. Range includes: AR, IL, IN, KY MO, & OK.
    • Magicicada tredecim (Walsh and Riley, 1868). Range includes: AL, AR, GA, IL, IN, KY, LA, MD, MO, MS, NC, OK, SC, TN & VA
    • Magicicada tredecassini Alexander and Moore, 1962
    • Magicicada tredecula Alexander and Moore, 1962
  • NOT the green cicadas that arrive annually.

Brood XIX has a 13-year cycle. It is interesting because it features both Magicicada neotredecim and Magicicada tredecim. These cicadas are very similar in song and appearance, but in areas where they overlap, Magicicada neotredecim alters its song to a higher pitch, which allows female cicadas to determine the species of their prospective mates. Visit Cicadas @ UCONN (formerly Magicicada.org) for more info on this behavior.

M. tredecim also have more orange on their abdomen than M. neotredecim.
Compare 13 year decims

When: Typically beginning in mid-May and ending in late June. These cicadas will begin to emerge approximately when the soil 8 inches beneath the ground reaches 64 degrees Fahrenheit. A nice, warm rain will often trigger an emergence.

Other tips: these cicadas will emerge after the trees have grown leaves, and, by my own observation, around the same time Iris flowers bloom.

More Location Tips:

Why: Why do they stay underground for 13-years? The prevailing research suggests they’ve evolved a long, 13-year lifecycle allowing them to avoid predators that would sync up with their lifecycle & emergence. Why are there so many?! Research suggests that their huge numbers allow them to overwhelm predators, so enough of them will live on to breed and perpetuate the brood.

Look out for Brood II, Brood V and Brood XIX Stragglers

Filed under: Brood I | Brood II | Brood V | Brood XIX | Magicicada | Periodical | Periodical Stragglers — Dan @ 6:31 pm

When is a 2012 Magicicada not a Brood I cicada? When it’s a straggler.

A straggler is a periodical cicada that emerges in a year before or after the year they are supposed to emerge. Typically a straggler will emerge one or four years before, or one year after the year they should have emerged. Stragglers from Broods II (due 2013), Brood V (due 2016) and Brood XIX (backin 2011) are or will emerge this year in limited numbers.

Brood II is set to emerge next year in most of central Virginia (as well as CT, MD, NC, NJ, NY, PA), Brood V will emerge in four years in Virginia and West Virginia (as well as OH, PA), and Brood XIX emerged last year in a few areas of Virginia (as well as AL, AR, GA, IL, IN, KY, MO, MS, NC, OK, SC, TN).

Stragglers present a challenge for people tracking the Brood I emergence because Brood II, Brood V and Brood XIX stragglers will emerge in the same states as Brood I cicadas. Brood II and Brood V overlap Brood I in some places.

Here is a comparison of the I,II & V Broods. The black dots represent where the cicadas have emerged historically.
