Need help identifying this bug

[Tom McLemore]

Does any body know what the name of this bug is? I find them on my cucumbers quite often. They don't seem to hurt the plant but I can't seem to figure out what they are doing. Any help would be useful...kind of cute actually.

Thanks for the info guys, I don't know if I'm likely to change my lazy gardener ways but it's good stuff to know.
