This yellow and black beetle looks like a newcomer to my garden. I wonder what he does. Anybody know his name?

It's definitely a longhorn beetle. The beetle u/Zapped mentioned, Rutpela maculata, looks really close with the yellow legs, but I'm not 100% as they have a tapered body since they mimic wasps and your guy doesn't look all that tapered to me.

The Four-banded Longhorn Beetle looks similar but it doesn't have yellow legs.

Other information: He was standing on the leaf of a squash vine.

How do you know this? Did you take a class on insects? Or describe it in google?

Google searched "yellow and black beetle Arkansas".

Thanks to /u/Zapped and /u/Musky for helpful tips on identifying this beetle. Based on what I read, I do not think I should be concerned about it damaging the squash plants. They might eat rotting wood.
