Matt Kason, a fungi researcher at West Virginia University, has discovered that cicadas whose bodies have been corrupted by the fungus Massospora keep flying around, have tons of energy and get really horny, because the fungus is doping them with meth and shrooms.

I asked Kasson if it’s possible to get high by eating Massospora-infected cicadas. Surprisingly, he didn’t say no. “Based on the ones we looked at, it would probably take a dozen or more,” he said. But it’s possible that earlier in the infections, before the conspicuous saltshaker stage, the fungus might pump out higher concentrations of these chemicals. Why? Kasson suspects that the drugs help the fungus control its hosts.
Infected cicadas behave strangely. Despite their horrific injuries, males become hyperactive and hypersexual. They frenetically try to mate with anything they can find, including with other males. They’ll even mimic the wing-flicking signals of females to lure males toward them. None of this does them any good—their genitals have either been devoured by the fungus or have fallen off with the rest of their butts. Instead, this behavior only benefits the fungus, allowing its spores to find new hosts.
Kasson suspects that cathinone and psilocybin are responsible for at least some of these behaviors. “If I had a limb amputated, I probably wouldn’t have a lot of pep in my step,” he said. “But these cicadas do. Something is giving them a bit more energy. The amphetamine could explain that.”
Psilocybin’s role is harder to explain.
Late August, and the roar of the crowd is unmistakable. It’s the season-ending song sung by the largest chorus imaginable: the Cicada.
Growing up in Queens, New York in the 1960s and ’70s, you heard pretty much nothing in the evenings except for the tinkling of the Mister Softee ice cream truck. Not even crickets.
Then one day on an August trip to the hoity-toity shopping street Omotesando Avenue in Tokyo in the late 1980s (having just left “Crayon,” my favorite children’s book store), I continued up the street through Harajuku and heard what sounded like a locomotive bearing down.
This was the entrance to Yoyogi Park, with wide and majestic tree-lined walkways that lead to the shrine Mejii-Jingu. If you find yourself there in the summer, make sure to investigate the gardens, which you enter for a slight extra fee—they are a mystical place where the koi mouth hello.
The heat and humidity was crushing, and the sound of what must have been millions of cicadas was overwhelming and surreal. A few steps off the street and under the verdant canopy, the sounds of Tokyo’s traffic had vanished, replaced by the roar of the crowd.
The cicada is a remarkable insect that grows in the earth, subsequently clawing its way through the soil, dragging itself up the bark of a tree. It resembles a prehistoric creature, something horrible resurrected from a comic book, and then it digs its crab-like front claws into the bark. Shortly its head splits open and an entirely different figure emerges, large and winged. Read the rest

So here is another line to kill space
This summer, folks on the East Coast of the US will see (and hear) an invasion of billions of cicadas in what is probably the most obvious part of the insects' 17-year life cycle. The cicadas will crawl out of the dirt, make a lot of noise, and seek out other cicadas in order to breed and create a new generation of larvae that will, 17 years from now, emerge to do the same thing all over again.
It's big news for those of us who think things like insects, evolution, and cyclical processes of nature are really, really cool.
Today, I ran across a number of Cicadasplosion-related stories and wanted to share them with you:
• First up, Carl Zimmer has a piece in the New York Times about cicadas and the evolution of seemingly strange life cycles. It includes a neat, interactive graphic showing a century of cicada blooms around the United States.
• The University of Maryland has a helpful cicada cookbook, including tips on the best times and ways to harvest the bugs. You want them young, and succulent, apparently.
• Cicadas will not hurt you, but they might land on you and there's a possibility that they may be sexually attracted to the sound of your weed-wacker.
• In 1894, The New York Times suggested pressing cicadas into a biscuit for dog food. Read the rest
