Tiny orange worms on bean plant leaves.

Does anyone know what type of worm this is and how I can eliminate them? This photo (see link) is a leaf I have just removed from one of my bean plants. These tiny worms are on the underside of the leaves. Thanks.

It's not in good focus and I can't see, but my best guess is Mexican Bean Beetle larvae. Are they bristly? Have you seen ladybug like yellow orange beetles with lots of (too many) black spots?

If there are not too many, you can just go around squishing them. If you are not up to it, you can drop them in a cup of soapy water. They are usually on the underside of where the holes are.

Thanks for your advice. I checked out your suggestion of Mexican Bean Beetle larvae. Not close to what I have. These are tiny orange worms, about 1/16 inch in length. If it helps, I'm in Southern California.

I can't tell you what they are, but you had best get rid of them if you want your plants to produce. I will suggest:

Do the worms move? If you can get a magnifying glass and describe the shape it would help.
It could still be Mexican bean beetles. The eggs are orange. Bean roller eggs are also orange.
Some aphids are yellow, but the distribution on the leaf does not look like aphids.

Whatever they are, they are not likely to be something you want to keep around.
