Magicicada Brood XXII, the Baton Rouge Brood, emerged in Louisiana and Mississippi, as well as Ohio and Kentucky, in 2014.
Update June 19: Signs of flagging from cicada egg laying are showing up.
Update (5/23): with folks reporting in from both Louisiana and Mississippi, it’s fair to say the emergence is in full swing. Go out and enjoy them while they’re still around.
Update (5/13): we’ve heard the first report that the cicadas have started singing! In Denham Springs, at least.
Update (5/5): the first confirmed Magicicada exuvia (shells/skins) have been found, as reported by Dave Marshall. It’s been a slow start thanks to a cold spring and cool soil temperatures.
Update (4/26): the first sightings have appeared on Cicadas @ UCONN (formerly Magicicada.org). If you see (or heard) one of these cicadas, report it. And then share it via Twitter, YouTube, Flickr or Facebook so we can all check it out.
Some Brood XXII facts:
- Brood XXII Magicicadas have a 13-year life cycle.
- Three of the four 13-year Magicicada species, M. tredecim, M. tredecassini, and M. tredecula, belong to Brood XXII.
- The last time Brood XXII emerged was 2001.
- We received reports from Baton Rouge, LA, Houma, LA, Pride, LA, Weyanoke, LA, Vicksburg, MS and Natchez, MS in 2001
Looking at the Cicada Central Magicicada Database:
- The following parishes in Louisiana will surely experience the Brood XXII emergence: Catahoula, East Baton Rouge, East Feliciana, West Feliciana. There are also literature records (typically older, and not substantiated by recent evidence) that the cicadas will appear in La Salle, Livingston, Pointe Coupee, St. Helena, St. Tammany, Tangipahoa, and Washington parishes.
- In Mississippi, Brood XXII should emerge in Adams, Amite, Claiborne, Hinds, Jefferson, Warren and Wilkinson counties, with literature records for Franklin county.
A lot of folks ask if they will appear in Orleans parish, but I haven’t seen evidence for that. However, there is no reason why you couldn’t start looking there, have some gumbo and fancy drinks, and then head north towards Baton Rouge.
These cicadas often appear where they aren’t expected and are absent where they are expected. So, keep an eye and ear out for them, but don’t be too disappointed if they don’t show up in your town.
