Periodical cicadas (Magicicada) are emerging in and around the Oklahoma City area, unexpectedly!
The Facebook page for this event posted that there are Oklahoma State University records of going back to 1996, 1979, 1962, and 1928, showing a 17 year pattern. There’s also some confusion between this “micro brood” [a term I'm using because I like beer] and Brood IV, because the Oklahoma M. cassini have orange stripes like an M. septendecula, and you can only tell them apart by their DNA (and their song, of course).
Magicicada.org had a Facebook update as well.
Chris Simon says they “think that this might be an undiscovered brood that just happens to coincide with Brood II.”
Thanks to T. Wilken for posting this image. it is a male M. cassini.
I checked the document Drew, W. A., F. L. Spangler and D. Molnar. 1974. Oklahoma Cicadidae (Homoptera). Proceedings of the Oklahoma Academy of Science. Stillwater. 54: 90-7. No specific mention of Oklahoma county.
There is an Oklahoma 17 Year Cicada Early Emergence Facebook page. (They might be 13 year cicadas, BTW).
- They could be Brood IV, which are due to emerge in 2015, making this a two year acceleration that brood. This could also be Brood XIX, which last emerged in 2011, making this a two year deceleration.
- They could be an undocumented emergence of Brood II.
- But the really weird thing is, Oklahoma City is outside of the Brood IV and Brood XIX areas.
- Did some windy weather move the cicadas westward?
- Did a nursery in the Brood IV or XIX area inadvertently move them to OK City?
- Did someone play cicada egg “Johnny Appleseed”?
