Hi Greg

Thanks very much for the photo and the information. Your specimen is definitely Okanagana species but I'm unsure if it is rimosa or canadensis as I recognize the pattern on the meso-thorax as distinct to both.

I will have to check my records to see which is known to be there in Wyoming.

Again, thanks for the information, it sure does help!

Currently I'm in Iowa mapping the western edge of Brood XIII. There's nothing like a Magicicada emergence!

I heard what I remembered from my childhood in Pennsylvania, the sound of a cicada. Could there be one this far West? I am in Laramie County, Wyoming and haven't heard that sound for about 35 years!

Hi Esther,

Actually, I'm not surprised that you are hearing cicadas in Wyoming. Wyoming like other states out west have very cool cicadas. In fact, if you heard a sound out there that you heard while in Pennsylvania is probably because it is the a similar species. Each cicada species has its own distinct calling song and there are many out west.

In thinking about what I know of cicadas in Pennsylvania and cicadas in Wyoming, the closest match to what you heard may likely be Tibicen pruinosus. This is just an educated guess based on records that I have of T. pruinosus being in Nebraska and a species in Pennsylvania known as Tibicen winnemana. Both T. pruinosus and T. winnemana have a surprisingly similar call. Now all you need to do is catch one!

Moved to Dubios, WY 5 yrs ago and that first summer I was frightened by the swarm on my log home. We haven't had them as thick since. They seem to appear in June/July just for a 2week period then they die off. Have to sweep dead carcus from porches and driveway. They are creepy when they bump into you.

Hi Diane,

Yes cicadas are very "bumbly" fliers and can often crash in to you. Your western cicada sounds like a species of Okanagana. Okanagana species are what is known as "proto-periodical" that means that they emerge in large numbers probably anywhere from 4 to 10 years and in off years their numbers will be normal. You may have experienced one of these "proto-periodicity" seasons when you first arrived.

In the future should you find any of these cicadas, please think of Massachusetts cicadas and send us specimens and/or photos by filling out the "report a cicada or cicada killer" sighting form.

Thanks for sharing your observations.

Just found a Cicada in my front yard..actually, my dachshund did, and was terrified by it is very large and very noisy. As she went to poke it with her nose, the cicada began to put up a buzz with it's wings and my dog Lexie, took off running, with her tail between her legs, sobbing...(Greenville, SC)
