The Black Swallowtail caterpillar has an orange "forked gland", called the osmeterium. When in danger the osmeterium, which looks like a snake's tongue, everts and releases a foul smell to repel predators, as seen in second photo.
found this eating parsley
I spotted this in the Fragrance garden beside the Floral Showhouse on the Niagara Parkway. There were at least 3 of these caterpillars eating the parsley.
