Its a BABY POTATO BUG! No doubt! Have fun squeezing them and then pop orange goo. LOL No seriously get them gone before they RUIN your potato crop. Pop em or flick em in water and soap or dust if you have to.
I think that's a Colorado Potato Beetle larvae - not a nice bug! It is pesticide resistant, so hand picking is the best way to get rid of them. Your photo is a little fuzzy, so make sure it's not a good bug before you take action. Here's some information: http://en.wikipedia.org/wiki/Colorado_potato_beetle Check out the photo of the larvae to make sure.
FYI, this is a picture of a ladybug pupae, which looks a bit similar. You want to keep this one around to eat the baddies: http://en.wikipedia.org/wiki/Image:Ladybird_Pupate.jpg
Your best bet is to hand pick since they are resistant to pesticides. Not a nice bug!
A side note: make sure that your bug matches the ID before getting rid of them. Here's a picture of a ladybug pupa which looks a bit like your bug: http://en.wikipedia.org/wiki/Image:Ladybird_Pupate.jpg If it's one of those, you want to keep it to eat the bad bugs!
