Video of a black swallowtail butterfly caterpillar poking orange antenna out when touched. Something else that is interesting is that a large wasp just landed near and stung one of these larger caterpillars and the caterpillar was unaffected by the stings. We have seen wasps attack other types of caterpillars like monarchs and gulf fritillary caterpillars and they instantly turn to mush and are killed. I guess the black swallowtails are immune to wasp stings. Has anyone else seen this?
