  1. What is this? About 1/4" across, found in the house. Posted 4 years ago
    1. Sorry Johny, but for me the photo is too unsharp to tell. Posted 4 years ago
      1. You mean, you can't tell if it's A, B, or C? Or you have utterly no idea?

        i think someone who knows this species will recognize it from this photo, regardless of blurriness.

        1. Well, if you're sure it's an organism and not an object, all I could think of is some insect nest or fungus. Where in the house did you find it? Did it move on its own? Any description of structure, size, smell? Posted 4 years ago
        2. Also, it would be helpful for you to include your location. Posted 4 years ago
  2. urban LA.

    Someone over on https://www.thephotoforum.com/threads/can-you-identify-this-species.448967
    seems to have identified it correctly

    goat head / Tribulus terrestris

    'Also called puncture vine because of its sharp thorny caltrop-like fruits that are prolific at the end of its growth cycle, it is known for "puncturing" human skin.'

    Yup.

"Tribulus terrestris" is an annual plant in the caltrop family widely distributed around the world. It is adapted to grow in dry climate locations in which few other plants can survive. It is native to warm temperate and tropical regions in southern Eurasia and Africa.
