It could be a gummy worm with bristles. The early instar Atala caterpillar is less than 1/2” long with aposematic coloring—rusty orange body marked with paired yellow dorsal dots. Zamia integrifolia, its host, has thick, leathery leaflets from which the younger instars eat the green flesh, leaving a brown framework. Later ones consume entire leaflets.
