You've probably heard that daddy longlegs are the most venomous spider alive, saved only by fangs too small to break your skin. Every part of that is wrong.
The common daddy long leg isn't a spider. It's a harvestman, a different arachnid with one round body instead of two, and it can't spin silk. It has no fangs or venom glands.
But you should love it anyway. It spends its days eating dead bugs and rot off the ground, which makes it part of your yard's cleanup crew.
If you see one of these guys in your yard, don't squish it! Count yourself lucky.
