Heraclides anchisiades
A lot of caterpillars in a citrus tree leaf. High speed video(160fps) included shows the defense organ in action, Osmeterium, that produces a bad smell.
Here is the butterfly from these caterpillars: http://www.projectnoah.org/spottings/885...
Thanks bayucca for the "osmeterium" tip in the other Swallowtail picture.
Really interesting. The mechanism was unexpected, especially as it came from one next to the one you touched!
