Pests on Potatoes

[Cynthia]

I have light brown spots on some potato leaves
A few leaves have holes in them - that's probably pill bugs
I found a long beetle on one of the leaves - NOT a potato beetle.

Any idea on what might be bugging the potatoes?

Blister beetle, maybe? Is it elongated with a white-ish or yellowish strip down its back?
