A couple weeks ago I was in the kitchen and whatever it was in the corner next to the desk did not look right for just a bit of the debris that has been following me in from the garden. So I looked closer. Then went for the camera and the bug jar. It was a scorpion that had managed to get its tail tangled in a spider web. Since it was still alive, I got it into the bug jar after I got its photo and then took it out to the front hill for release. The scorpion looked a little worse for the experience, but maybe was the winner of the battle. Some time later I went to sweep up and found a dead spider in that same corner. Perhaps the scorpion managed to sting his opponent before he was snagged in the web.
We seem to find one of these somewhere in the house every few years. One prior visitor had gotten its sting hooked in the family room carpet and the threads needed to be cut to free the critter. A couple others just appeared in the middle of the hallway or even an upstairs bedroom. How they get to where we find them remains a mystery.
