Brood XXIII, the Lower Mississippi Valley brood, will emerge in 2015

The Latest:

Most popular question in the comments: “how long will they last?” The typically answer is about 4 weeks of singing or less. They sing to meet a mate, and once they mate a few times, they run our of energy and die. Four weeks is the typical time, although this varies depending on weather. The cicadas will complete their mission faster if there are more dry, calm days in with temps in the 80s.

My gallery of photos from Brood XXIII.

The Giant City State Park area of Illinois was loaded with cicadas. This area has all four species. It isn’t easy to tell the difference between M. neotredecim and M. tredecim, but you might notice a difference in the coloration of their abdomens (tredecim is almost all orange, while neotredecim is orange and black). There is also a difference in the pitch of their calls when they are in close proximity, so you might hear an odd dissonance in their calls. M. tredecim pitches lower. I will post photos, videos and sounds later in the week.

There are plenty of cicadas in the Land Between the Lakes area of Kentucky & Tennessee. The best place so far was Kenlake State Resort Park where M. tredecassini, M. tredecula and M. tredecim are chorusing. The tredecula and tredecim were up in the trees out of reach, but I was able to find a few tredecim (the bigger ones with very-orange abdomens) in the weeds at ground level. Here’s a map of where I’ve heard the cicadas so far.

Cold and rain (and road weariness) has prevented me from locating cicadas in Texas, Louisiana and Arkansas — I know they’re there but if I can’t hear them, I can’t investigate. I’m headed north to Tennessee, Kentucky and Illinois. Sun and temps in the 80s should make for good cicada observation. If you’re wondering why cicadas have suddenly become quiet, it’s typically because of cold temps and rain. Generally, these cicadas like it to be about 77F before they’ll fly and sing. Colder than that, and they’ll chill.

I arrived in the Jackson Mississippi area on May 19th around 3pm. M. tredecassini were chorusing along route 20 west of Roosevelt State Park, and I found an M. tredecim (below) at a gas station. There were plenty of M. tredecassini and M. tredecula chorusing and courting in the woods behind the Mississippi Museum of Natural History. Neocicada hieroglyphica (a non-periodical cicada) were also calling in the woods.

The 2015 Brood XXIII is well under way! The first photo showed up on flickr, and first sighting (Mississippi) has showed up on the Magicicada.org map.

About Brood XXIII:

Brood XXIII, the Lower Mississippi Valley brood, will emerge in Louisiana, Mississippi, Arkansas, Tennessee, Missouri, Kentucky, Illinois, and Indiana, in the spring of 2015.

Species:

The cicada species that will emerge are Magicicada tredecim (Walsh and Riley, 1868); Magicicada neotredecim Marshall and Cooley, 2000; Magicicada tredecassini Alexander and Moore, 1962; and Magicicada tredecula Alexander and Moore, 1962. These periodical cicadas have a 13-year life cycle. The last time they emerged was 2002. According to John Cooley of Magicicada.org, Giant City State Park, Illinois is a good place to observe both M. tredecim and M. neotredecim.

13 Years ago:

Back in 2002, the emergence began in the last week of April, 2002, and ended the beginning of July. You can read what people said about them back in April, May, and June of 2002.

2015 Periodical Cicada Emergences

Filed under: Brood IV,Brood XXIII,Magicicada,Periodical Stragglers — Dan @ 1:06 am

There will be two major periodical cicada emergences in 2015. We’re less that 2 months away!

2015 BROOD IV AND XXIII

Brood XXIII, the Lower Mississippi Valley brood:

This brood of 13 year Magicicada will emerge in Louisiana, Mississippi, Arkansas, Tennessee, Missouri, Kentucky, Illinois, and Indiana. Brood XXIII features all four 13 year Magicicada species M. tredecim, M. neotredecim, M. tredecassini and M. tredecula.

When they’ll emerge depends on the weather. A cool spring will mean the emergences will start later in the spring. Regardless of the weather, the emergences will begin in the Southern-most states, sometime in late April or early to mid May.

Brood XXIII should, depending on the weather, start emerging in less than two months; some time in late April in Louisiana.

Brood IV, the Kansan Brood:

This brood of 17 year Magicicada will emerge in Texas, Oklahoma, Missouri, Kansas, Nebraska, and Iowa. Brood VI features all three 17 year Magicicada species M. septendecim, M. cassini, and M. septendecula.

Brood IV should start emerging in early May.

Brood IV and XXIII won’t emerge in the same year again until the year 2236. The only state that features both Brood XXIII & IV is Missouri, but the areas where they emerge do not overlap.

Stragglers:

The best bet for Stragglers will be Brood VIII (17 year cicadas emerging 4 years early) & XIX (13 year cicadas emerging 4 years late). There is also a chance for III (17yr/1 year late), V (17yr/1 year early), and XXII (13yr/1 year late). Visit our brood page, to see the states where these stragglers might emerge.

Magicicada cassini calls, chorusing & responses to finger snaps

Filed under: Brood II,Magicicada,Periodical,Sounds,Video — Tags: — Dan @ 8:00 am

During the Brood II emergence in 2013, Elias Bonaros, Roy Troutman and I spent some time experimenting with coercing male Magicicada to call in response to finger snaps, which mimic the snap of a female cicada’s wings. This trick works fairly well with Magicicada, and can quickly be mastered once you work out the timing. Fingers, wall switches, and the zoom button on my Sony video camera do a good job at mimicking the snap of a females wings.

I also recorded their calls in terms of decibels to see just how loud they could get. They can get very loud, but not as loud as a rock concert (see this db chart).
