Comments & ID Thoughts

I live in Arizona in Scottsdale and I found this spider crawling on my leg when I was sitting on my couch I never even felt it crawl up my foot or anything I just saw it and he was huge in person, I flicked it off my leg onto the carpet put a glass over it and then let him go outside, does anyone know what this spider is?

You have impressive self control to just flick something that size crawling on your leg. Thank you for not harming it!

Well, thanks for respecting spiders, crawling on me, I would likely coax it onto my hand and take it outside,,provided it doesn’t spook, they can be easy to pick up.
This is a video with a giant house spider, but the technique works for a good number of spiders:

A different type of huntsman, but not much different catching them:
