We found a Acadia here in Kalispell, Mt. Never seen them before, had to look it up to identify it.
We live in columbus montana and found cicadas on our trees never saw them before how often do they come around lived here my whole life
Thanks for sharing your experience!
Earlier this summer (2022) here near Helena, Montana there was a very massive emergence of a species of cicada that I think occurs only once every 5 to 13 years, I cannot recall the year that such an emergence occurred last time, but I’ve lived here 28 years and only noticed them once or twice before. I can still see many nymphal exuviae mostly around sage brush but I saw less than 10 adults back in July and I cannot find the corpse of an adult at all so that I can identify the species. The literature says that there are no periodic cicadas this far west!?
There are no periodical cicadas in Montana, but there are cicadas like Platypedia putnami keddiensis Davis, 1920 that have bumper crop years and years with very few cicadas. This can be based on weather fluctuations or density and competition underground
