I am wondering if anyone knows what these little Caterpillar looking bugs are that are all over my elm tree. Also is the other photo associated with the bugs, or something different? Thanks in advance

Is that a Siberian Elm? If it is it is one of the most repugnant trees in existence. It has no reason for being in the US.

Judging from your location, I agree with the above post. I'm in northern Utah (Salt Lake City Metropolitan Area) and this is one of the most widespread urban (and rural) weeds here. It is originally from the high deserts of China, Mongolia, Kazakhstan, and Russia which have a very similar climate to the western United States, which is one of the reasons it seems to thrive here. I've read that in its native range, it is long lived but here in the U.S. it is prone to pests and diseases.
A picture of the whole tree could help confirm its identity, since Siberian Elms have a rather irregular form.

I grew up with this repugnant tree as a child here in TN. Always attacked by pests and oozing sap and limbs dying. It was a horrible sight. My clueless parents planted them and I have no clue where they got them. In my early 20s I got rid of them and have rarely seen them since. I don't think any reputable nursery would dare sell them. They are a true horror.
Maybe they fill a niche in Siberia. Definitely not here.

The other photo could be wetwood or slime flux, compare with these images.

It's not likely to be from the caterpillars. Are the caterpillars eating the leaves?

Thank you everyone for the input. Still not sure of the yellowish looking work like bugs in it tho. I'll try to find a clearer pic of them

Might be elm leaf beetles. See any of these?

Good thought, Rob. There's a picture of the elm leaf beetle larva here:

Thank you all, I do believe that is what they are. I also think that the tree is beyond saving. It was this way when we moved in here, and has progressively gotten worse every year.

Now is a good time to have it removed, to plant a really nice tree.

This may be a small adult of the beetles. This is the best picture I've got.

If you want to treat the tree, you can spray with Azamax, neem oil, or spinosad. These are safe, but the spinosad will kill bees FYI.

That looks like this guy, European elm flea weevil. So not the adult of those other larvae.

Yes. Cut it too the ground and spray the stump with a cheap glyphosate. Not Roundup brand which is 2 or 3 times more expensive than generic glys.
And watch out for root suckers.
