    This is a really cool video because you get to see the transformation at the end where they change colors from the teneral pale color to the beginning of the darker final color. Thanks for sharing and I hope this one was treated humanely and allowed to go out and find their mate.

    Loving these videos so far, they’re a great resource. I do have to say though, I very much disagree about arachnids not making good pets. Sure they’re not cuddly, but neither are fish. You don’t get a scorpion or tarantula and expect it to act like a dog, they’re beautiful to admire and observe. I have an Asian forest scorpion and an amblypygid and they’re both delightful little fellows to watch. That being said, I still very much appreciate having these lectures on RUclips, they’re great to watch and have to learn about arthropods so thank you for uploading them.

    Oil would hel to control it?

    • @daveshetlar4651
      @daveshetlar4651 3 года назад

      Horticultural oils (mineral and plant oils that are designed to be applied to green plants at low rates) will kill most mites, but only by contact. Many of the eriophyid/rust mites are in galls or deeply imbedded in plant folds, so hitting them with oils can be very difficult.

    Great lecture! Entomology is so fascinating, they're like Pokemon! I'm a chemical engineer with a nanotechnology background and I went to a school renowned for entomology. I was able to see how often we refer to bugs for complex engineering design -if I could go to school forever after my PhD, I'd go straight back for an entomology degree!

      Probably not dangerous, but being on an oak, it would likely be full of bitter tannins.

    The actual process takes about 6 minutes from starting to take a gather to finish (putting it into the lehr). There are usually two to four people taking gathers and walking each piece through the process. This is slower than the pressed pieces that Fenton made where there might be five to six handlers and one or two finishers. This would mean that they would produce a piece every minute or less while these blown molded pieces would be a piece every two to three minutes. Each piece may take three to six hours in the lehr (an oven that slowly cools the piece to remove internal tension), depending on the size and form.
