Yes, spiders have at least two methods of flight. One method they have is to use a spider-silk thread that carries them on the wind. The other, I discovered recently, is to use their legs. I was walking on a newly-paved stretch of path, minding my own business, when I noticed coming up along-side me a strange-looking bug. At first, I thought it was a flying insect, but it didn't look like any flying insect I'd ever seen before. It was just hovering along-side me at eye-level, going just slightly faster than I was walking. I inspected it a little closer... it was a spider! It had the look of a top-heavy flight plane where the wings are fully under the body. The 'wings' were actually the spider's spindly little legs tremulously undulating in the wind. It appeared to be attempting to follow the same pathway I was following and eventually I watched it land a few feet in front of me on the pavement. I was able to say 'hi' and get a closer look. It wasn't timid at all but kept trying to climb up on me. Maybe it thought it would get a free ride! Now I have a new respect for spiders with spindly legs. ❤️
