Most cicadas have a special organ called a tymbal they use to make the incredibly loud calls that pulse through summer afternoons. But Putnam’s cicada is different; it belongs to a genus known as wing-tapping cicadas, and its sounds are just that.
Having an unusual sound gives wing-tappers their own audio niche as they try to stand out in their search for a mate.
“There's all of this sound specialization,” Gharbi said of insects in general, “where they're all competing with each other for the same sound space. And so to minimize competition, they each take on their own specific frequency, sound [and] rhythm. They're all basically … making sure that they can still be heard in this cacophony of insect noise.”
Suspect number three: None of the above
At the end of the day, without an actual specimen, it’s impossible to say for sure what Garfinkel has heard, or whether the sound has come from just one type of insect.
“A lot of animals can click,” Garcia said. “So if you don't see the actual beetle then, I don't know, maybe it's not necessarily that kind of beetle.”
But the internet does have lots of places that will try to help you Shazam any insect sounds you’re hearing, if you’re willing to work at it.
Songs of Insects provides little audio clips of crickets, katydids, grasshoppers and cicadas, with delightful descriptions such as “A plaintive, dissonant trill from trees at night.”
iNaturalist, Gharbi’s Pokedex of living things, allows users to upload, ID and discuss all sorts of creatures they run into out in the world.
And for Colorado-specific insect curiosities, Colorado State University’s Extension has information on all sorts of invertebrates: pests, pollinators and much more.
But with fall fast approaching, there isn’t all that much time left in the year to wonder over those clicks and calls from the underbrush; the first Colorado cold snap will silence much of that chorus until their offspring emerge next spring.
