Swarm of Cicadas Takes Aim at U.S.

wetshoe writes "'After 17 years of relative quiet, Mother Nature is bringing the noise. 'Periodical cicadas, a species of the grasshopper-like insects best known for the scratching, screeching "singing" of the males, will emerge this May, filling forests in more than a dozen states. Almost as abruptly as they arrive, they'll disappear underground for another 17 years.' The article also talks about areas in the Mid-West where 17-year June Bugs sometimes overlap with 13-year June Bugs. I remember as a child one such time, you literally couldn't walk anywhere without stepping on them, they were everywhere. Reminded me of a biblical plague."

      I remember many years ago riding thru parts of Iowa and Wisconsin and having to stop to clean my helmet off every few miles, especially if I was riding during the early morning hours (the best time to ride on hot summer days). You'd be flying along just fine, then there'd be a concentration of the little beasties, usually down in low spots near creeks or rivers, and it was like being sandblasted by paint gun slugs. Within a half mile you'd have to pull over and scrub your helmet visor, preferably with muriatic acid (joke, some bug juice is incredibly hard to remove) and try getting the bug juice stains out of your leather...argh.

      That said, grasshopper swarms are much, much worse. Run into one of those at 80mph and it can be dangerous... a friend back in '88 ran into a particularly thick swarm near Mason City and was blinded almost instantly, resulting in him laying the bike down at over 60mph. He was lucky it was a typical water filled Iowa ditch he ended up in. Trashed the bike, tho.

  9. Prime numbers by CalCudahy · · Score: 5, Informative
    I remember reading an interesting essay by Stephen Jay Gould on why these species that only emerge periodically do it at prime number intervals. The problem is that they have to swarm in such huge numbers to overwhelm any predators and multiply rapidly. To prevent a predator from evolving to depend on their "blooms" and wipe them out when they emerge, they only do it at prime number intervals. That way a predator would have to multiply in the same time interval and not some fraction of it. If it was 12 years a predator could multiply every 2,3,4, or 6 years and have a chance of feeding just when the cicadas were blooming. It's a lot less likely that a predator will multiply at only 17 years at the same time as the cicadas.

    There are also species of bamboo that periodically produce tons of seeds to reproduce, but on the order of every 70 years. These too only do it on prime number years.

    Who knows if he was right, but it is a cool theory.

      Hmm. Interesting.

      My only objection is that it explains why the times are prime, but not the coincidence of them all being 17 or 13 years.

      Each of the three 17-year varieties' closest relative is a different one of the four 13-year varieties, not another 17-year one. We would therefore, evolutionarily, expect that the ancestral periodic cicadia first divided into at least three species, and then each of those three divided into 13 and 17 year varieties.

      So why did each of the three branches evolve both 13 and 17 year terms, but none evolved the equally prime 11 or 19 year terms? 11 and 13, or 17 and 19, are both seemingly more likely pairs than 13 and 17. Why did it become 13 and 17 three times?

    It's a neat theory, and it is probably true that species with life cycles which are a prime number of years have an evolutionary advantage over those whose cycles are evenly divisible, but the advantage is slight enough that his assertion there are only species with life cycles that are prime numbers is wrong.

    Quoth the article:

    Question: What is the life span of a cicada?

    Answer: That depends on the Genus and species of the cicada. The Magicicada Genus of North America has a 17 or 13 year life cycle (the largest of any insect). Other Geniuses of cicadas have life cycles of a variety of years (never more than 17 and usually a primary number). The Tibicen or "dog day" cicada has a life cycle of only a couple of years and which is one of the reasons why we see them each year.


    Most are prime number cycles (probably as a result of the advantage vis-a-vis cyclic predators you cite), but NOT ALL.

  14. No BB guns? (and other memories) by Stonent1 · · Score: 3, Informative

    I can't believe that no one here has mentioned shooting them with BB guns during the summer. I never did but I saw several people do it. These things are easy to catch. You just pinch their wings between your thumb and forefinger and they can't do anything. We have green ones in Texas every year, they are the most common. (They black and yellow zig-zags on their head) From time to time I see very large brown/orange ones which only seem to come out at night. I've also seen a few solid black ones that were the size of the green ones. Once I even caught an extremely tiny one that was no bigger than a coffee bean. Each one seems to have their own special call. (Only males can call) The greeon ones in Texas have a rising and falling sequence that takes about 7 seconds. The large brown/orange ones alternate wee-oh-wee-oh-wee-oh. The solid black ones seem to have a long high pitch call. When you try to catch cicadas they will sometimes spray you with a drop of clear liquid. I assume it is either urine or reproductive juice. Males are easily identified by their sound. (Females are silent) Males also have breast plates which vibrate to make their sound. Females have none. The females end in a point, and if you flip them over they have a black line extending to the point. Males have an organ (I assume a sort of penis) that flips out from their tail end.

    During the summer, you can find their shells all over the place. They emerge with their wings folded very tightly and take about 12 hours to unfold and dry.
