Due to the
- chewing mouthparts,
- the greatly developed femurs specifically adapted for jumping (what fits well with the OP's observation of jumping behaviour),
- prominent compound eyes and
- long, filamentous antennae
we can conclude that this specimen is an orthopteran insect larvae.
Well known members of this insect order are grasshoppers, locusts and crickets.
Orthopterans undergo incomplete metamorphosis, progressing through egg, nymph and adult stages. Nymphs often resemble adults, but lack fully developped wings and reproductive structures. As this specimen lacks wings, we can conclude it must be a larvae.
Moreover, I assume this specimen belongs to the suborder Ensifera as its antenna are longer than its body (as opposed to their sister taxon Caelifera which have antenna shorter than their body).
It's often tricky to identify species from photos, so no guarantuee on that, but a genus with similar larvae would be Scudderia, the Bush Katydids, which is present all over the US with following similarities:
- the "hat" with a dark lateral line
- 1st antenna segment brighter than the others
- 1st and 2nd antenna segments roundish
- remaining antenna segments long, slender and dark with white ends
- black eyes
- white "cheeks"
- typical slender, long legs with dark and bright coloration
- the fine spines and hair all over the body
