A velvet worm (lighter in color)—an arthropod-relative so unique that it is classified within its own phylum, Onychophora—and caterpillar of unknown species (darker in color) interact after being found near each other in the Amazonian cloud forest in Ecuador. The caterpillar is proposed to be a Batesian mimic of the velvet worm. Both were discovered by a team of researchers and students from Western University in Ontario and reported in the Summer 2018 issue of American Entomologist.
