What is eating my Sqaush? They look like tiny yellow caterpillars!?

Question

They aren't Squash Beetle, Squash Bugs, or Squash Borers from what I can tell. They are about 1/4 to 1/2" long and they are smooth with six or so feet. They are bright yellow. Regardless of what they are, how can I keep them from ruining my crop?

Answer 1

Kathryn I would say it is leaf miner larva.  Check picture in Flickr.
