Mystery Holes in Pine (Pinus sp.) Bark I found a pine tree with tiny holes in the bark. I pulled a piece of the bark off and found a little case attached to the hole (see additional photos). I couldn&#039;t see it at the time, but there was something in the case. So far, I don&#039;t know what it was. <br />

  1. Nice finding! Posted 3 months ago
    1. Thanks :) Posted 3 months ago
  2. Any theories so far? Insect cocoon? Posted 3 months ago
    1. I think it is some kind of cocoon or hibernation site. There is definitely an insect inside and I wish I had taken a closer look to see what it was. There were a bunch of these holes in this tree, so I'm going to go back and see what I can find once the trail opens back up. Posted 3 months ago
      1. Awesome, hope you keep us updated :) Posted 3 months ago
        1. Definitely! This tree is in a pine forest, so hopefully I can find it again. I'll have to use my autistic radar, haha ;P Posted 3 months ago
          1. Just find the pine, Christine, how hard can it be in a pine forest. Posted 3 months ago
            1. Lol, easy! Posted 3 months ago
  3. The more I look at it, the more mysterious it gets. Upon a better look it does look like an insect yet semi-mature, also the "house" is quite oversized. Posted 3 months ago
    1. Exactly. It doesn't look like a larva in there. Also, the hole to the "cocoon" was perfectly lined up with the hole in the bark, which makes me think this could be a brooding chamber for an adult to lay eggs/overwinter in because if it was a cocoon, the end would have been sealed. But, since it was open, that makes me think that the insect comes in and out... Posted 3 months ago
      1. Could be one of the tiny pine bark beetles. Posted 3 months ago
        1. It definitely could be. It's hard to see, but it looks like a tiny adult insect is in there. Posted 3 months ago
          1. You should be able to tell once you get another look at these. I checked the various fact sheets from the USDA on pine bark beetles and none mentioned this structure so it may not be a pine bark beetle at all. Posted 3 months ago
            1. I just got a suggestion on FB that the insect inside may be unrelated to the cocoon. Or, it could be a parasitoid. Posted 3 months ago
