''Papilio rutulus'' can reach a [[wingspan]] of {{convert|7|to|10|cm|in|round=0.5|abbr=on}}. These large butterflies are brightly colored. The wings are yellow with black stripes and blue and orange spots near their tail, they have the "tails" on the hindwings that are often found in swallowtails.

Young caterpillars resemble bird droppings, and as they molt, they eventually turn bright green, with a pair of large yellow [[eyespot (mimicry)|eyespots]] with black and blue pupils. The [[chrysalis]] is green in summer and dark brown in winter, and looks like a piece of wood.

Even as caterpillars, they need to find a way to protect themselves from threats during their early development. In their caterpillar stage, they mimic a snake with the tongue like osmeterium ( a defensive organ ) and two eyespots on the thorax to ward off potential predators.
