Probably Colorado Potato Beetles. The adults as well as the larvae will eat the leaves. Spinosad works on the larvae if you get them when they are young enough. It does not kill the adults.
I grow potatoes and I handpick (smash them) the larvae daily. It only take me about 15 minutes a day to do my 3 rows of potatoes.
Look under the leaves for the distinctive clusters of bright yellow eggs.
