We're pretty good about checking our plants everyday, and it seems like these appeared overnight! Lots of them at least 20 all over my pumpkin plant. Any idea what they are. I Googled tiny red and black beetle but nothing really seemed to look the same. They have a black head and red round body. I assume they are bad of course, so I guess I've got some work to do.

Yikes ! Sue 😮👺👺👺!!!
Looks like, i belive. Squash bugs.
Squish what you find. And spray. They transfer wilt that cant be cured. Also, on bottom right corner of your pic. I see powery white. Could be thrips or ? Bug spray will take care of them also.
NOW !!! GET TO WORK !!!
😎😎😎

They look like they may be "true bug" nymphs but there are several with similar coloration and I can't make out the details. Is there any chance of getting one onto white paper so as to get a sharper picture (so the camera focuses on the bugs rather than the leaf?

They are the wrong colour for squash bugs, Philip, they look like this:

Thanks! I sprayed them and we actually just had some heavy rain, so I'll go take a look again tomorrow and see if I can get a better picture.
