My son and I just found these two less than a foot away from each other. I think we have the names right but I’m not sure.

Four Horned Sphinx Caterpillar

Dear Breanna,
Both of your identifications are correct, and we can even provide you with a species for the Sphinx Caterpillar.  Though the common name ignores the caudal horn present in so many Sphinx Caterpillars, the Four Horned Sphinx is also called the Elm Sphinx.  The leaves in your image appear to be elm leaves.

Location: North Texas
