      1998 was a hard-fought year. Luckily for us it was a La Niña year, and the cooler weather slowed the cicadas down. As a bonus, the governments were able to disguise the human fatalities as hurricane-related.
      With 200 years of global warming, it is anticipated they will come out of the ground the size of housecats, but move even faster.

    During my childhood in France, we had a lot of cicadas each summer and their song stays in me as the best souvenir, followed by all the horse chestnuts that were falling on the ground each autumn. We picked them up and play with them for weeks, making some little animal figures with them and with acorns.

They have no fear of anything no self defense they just repeat this with the males singing when a lady shows up. Smooth surfaces are probably their biggest "predators" with the cicadas trying to climb the surface only to struggle to get a foothold fall back down regain their bearings and then walk right back to try again until they either give up or exhaust themselves.

    The 13 year lifespan and the 17 year lifespan cicadas will interbreed at their respective frequencies, then every 221 years they're guaranteed to overlap and guarantee genetic variance and a population boon. Kind of a cool life tactic.

    • @Dragrath1
      @Dragrath1 3 ปีที่แล้ว

      There is apparently several species of periodical cicadas in my area they are past peak here but much of that peak was the largest species which all quickly emerged and did their thing. However then there was a smaller species of periodical cicadas that co time their emergence with the end of that spike in numbers they seem to be much more staggered with more emerging to fill the void of their dying brethren they also don't seem to have the same shade of red either.
      There is also a weird phenomenon where some percentage of the population will emerge early or late by either 1 or 4 years exactly. No one knows why this is but occasionally there is enough that emerge on these off years to set up a new viable brood. It is hypothesized this might have something to do with avoiding their fungal parasites.

    Nymphs know when they have it good. I grew up where they loved Mango trees (the underground part) and would come up to mate. They would first climb up the tree trunk and shed their nymph exoskeletons, which you could collect off the tree bark, before filling the grove with their deafening sound. I wish I had thought at the time to dig down around the roots of the Mango trees to see if the nymphs could be found to see how they related to the tree. Maybe some of you can do this and do a video.

    Southern AZ cicadas sound like every other North American cicada. If their noise was amplified and run through some kind of predator voice modulator. Also, they're around for the bulk of monsoon season. Not sure if individuals actually live that long though. Thanks to everything being crazier in the desert, they're around (in varying numbers) every year now.

    I find it fascinating that after say 15 years, they pretty much know the exact day, or at least week, that the cicadas will come out. They got it bang on right this year.

    Apart from human interference and the depletion of probable food sources, most birds commonly live up to 10 to 20 years. So, it makes perfect sense why the population crashes once the Cicadas emerge from hibernation; therein, Cicadas have learned to calculate the age expectancy of their enemies. And you wonder where Ninjask got its name.

      Cicadas typically don’t emerge until late summer. Only periodical cicadas arrive in the spring.

    If you define a prime number as a number that can only be divided by itself and one (as you do in this video), then that will imply 1 is itself a prime number, which it isn't. A prime number is a natural number that has just two distinct natural number factors. That rules 1 out.

  • @567secret
    @567secret 3 ปีที่แล้ว

    Due to the breeding cycles being coprimal, they will inevitably go through spacings in their cycles of 0 to 13 years, but what occurs when one of the cicada cycles occurs 1 or 2 years after the other and the bird populations are high in this period?

    For those not experiencing this, I'm in ground zero. They are LOUD. Their noise permeates through my house walls! They are everywhere. One landed on my shoulder and BRRRRRRRRRRRT. No, buddy, you are not mating on my shoulder so scram! I refuse to eat them as some suggest, but beware if you have shellfish allergy as these contain similar ingredients. And the 1yr brood has come up, so now they are competing in volume.

    Its also not coincidence that the Sun is on a prime number cycle too, 11 years. So there could also be a correlation between the Solar cycles and emergence cycles.

  • @SaltpeterTaffy

    "Their cycles tend to be one to ten years long."
    A one-year cycle should have no trouble syncing up with any cycle lasting a prime number of years. All prime numbers can divide by one.

    I propose marking your age by virtue of the number of periodical cicada emergence events you have witnessed. By a rough calculation, including both the 13 and 17 yr cycles, you get about 13 events before you die.
