  • During the fires last year, we learned that ground squirrels and rattlesnakes will den up together. Turns out that the ground squirrels have evolved an immunity to rattlesnake poison, so they are no longer on the menu. I’m sure there’s more than one lesson to be had in this…
    (Also, my vet says that cats are largely immune to the venom of the rattlers; that they’ll swell up and stay out of action for a day or three, depending on the bite site, and then make a complete recovery.)

  • Thank you for this very interesting video. It indicates so much that has been invisible to me.

  • Thank you Kim…this is super interesting! You said there were a dozen burrows of the tiger beetle larvae close together. Could it be because the female’s egg-laying pattern and method? Does she dig small burrows for the eggs initially?

    • Lauris, I think they lay the eggs in randomly placed holes. They don’t dog the whole burrow, as far as I know. The larvae digs (or widens it) as it grows.

    Thanks Kim. I’ve seen these little homes a lot in the same area as black trumpet mushrooms. Here’s a pic of a trumpet and a beetle burrow (I think). Been so focused on the trumpets that I never noticed 2 different types of burrows
