    Maybe they’ve known about them but haven’t been able to capture them until now

      They’ve observed this in a lab.

    Crane flies are a big deal where I live, and especially the ones with reeeeally long legs - longer than anything pictured in the Wikipedia article - just love to come into people’s homes, especially in September.

  Adrian Tchaikovsky warned us of this.

    Actually those spiders were pretty damn cool! And it’s an excellent book series.

      Oh, for sure. I hate spiders, and I was loathe to read it, but damned if I didn’t enjoy all of them.

    For a Sci-Fi newbie who’s thinking of trying out Tchaikovsky, any advice on where to start?

      Start off with the Children of Time series, there’s no reason not to. Well written, great story with memorable characters, and a fantastic hard sci-fi twist on what intelligent life really is, and how we think of ourselves and others.

  Hasn’t this been known for some time? Perhaps I’m confusing these spiders with ones that simply form wind sails.

    The most recent article in the post is about 4 years old. I definitely recall learning this a while ago.

    If you read any of the article OP provided, you’ll see that the common belief that they were simply using the wind was false and they actually use electric currents in the air.

  Is this study (afaik published in 2018, but the paper is dated or was amended in 2020?) distinct from the others? I’m guessing they detailed the “electric” part better?

  It is observed in many species of spiders, such as Erigone atra, Cyclosa turbinata, as well as in spider mites (Tetranychidae) and in 31 species of lepidoptera, distributed in 8 suborders. Bell and his colleagues put forward the hypothesis that ballooning first appeared in the Cretaceous. A 5-year-long research study in the 1920s–1930s revealed that 1 in every 17 invertebrates caught mid-air is a spider. Out of 28,739 specimens, 1,401 turned out to be spiders.

  Although this phenomenon has been known since the time of Aristotle, the first precise observations were published by the arachnologist John Blackwall in 1827. Several studies have since made it possible to analyze this behavior. One of the most important and extensive studies exploring ballooning was funded by U.S. Department of Agriculture and performed between 1926 and 1931 by a group of scientists. The findings were published in 1939 in a 155-page bulletin compiled by P. A. Glick.

    But how common are windless conditions, really? It seems incredibly rare that there would be so little air movement that the effect of it wouldn’t far overwhelm the electrostatic effect. I’m no meteorologist, though.

  Pictured is a banana spider, shitloads of them around here. Those are not flying. Looks like this one is making the zig-zag thing some orb weavers make.

  Cool fact! They’re also called Golden Orb Weavers because their webs shine gold when the sun hits right.

    Bananaspider is quite ambiguous and refers to multiple spiders.

    Golden Orb Weaver is the common name for Nephila (which this one is not), though often wrongly applied to Argiope.

    This one is Argiope aurantia, which as a bunch of common names including “golden garden spider”, but I prefer “black and yellow garden spider”.

  This spider is clearly on a mission, it has an objective and won’t let anything get in the way of it.

  Next they figure out that Dandelion chutes actually use charge differences to fly or something.
