Spiny crawler is what the Hendrickson mayfly (Ephemerella subvaria) nymph is called.
Specifically, the nymph is the immature developmental stage of the mayfly. It is what hatches out of the eggs laid by the female after mating with the male Hendrickson mayfly. It looks like a developing, smaller version of the mature Hendrickson mayfly.
