Tiger Swallowtail Caterpillar
Tiger Swallowtail Caterpillar

This is the caterpillar of a Tiger Swallowtail, and what you have mistaken for a tongue is a retractable organ called an osmeterium that gives off a foul odor.  The odor coupled with the false eyes may give predatory birds the illusion that the tasty caterpillar is actually a much larger snake that could be dangerous to a bird.  Your submission will post live to our site later in June while we are away on holiday.
