Found this on my cucumber leaves today. Should I squash it?

It certainly is, and you'll want to start thinking about control, or before you know it, you'll have tons of them.
How would you suggest to control it?
Thumb and first finger works well lol....
I have been doing this to the squash bug almost all day. My finger are all orange.
