Mature pumpkin vine leaves being eaten?

I've done all kinds of research and have checked for fungus, aphids, snails, slugs, etc., including checking the leaves at night....but the leaves keep getting profuse "track" marks, turn brown and die. Much fruit has started, getting to about the size of a walnut, but withers. Could the tiny little worm in the photo be the culprit? (for scale, it's on a clothes pin). I've only seen a few of them.... I hope the photos help. Thanks! ~Dan PS: I guess only one image is allowed.... the worm looks like an inchworm....skinny, green, less than an inch long.

I would guess powdery mildew

Could be mildew. Can you post a photo of whole plant? Does the browning and dying of leaves start at the base of the plant and spread from there?

The white marks to me look like leaf borer marks. There are a few different bugs that leaf bore. For the most part, not terribly serious. The leaves turning brown and dying is more concerning. I'm wondering if you have 2 dif things going on.

That's a really bad case of leaf miners. Here's a link on them. The problem is that they are actually inside the leaf, so most sprays won't work.

Tahlequah, OK
