The pipevine swallowtail is a black butterfly whose back wings shine bright blue in the light. Its caterpillars are black or red with orange spots and soft spikes. They eat a poisonous plant, which makes both the caterpillars and the butterflies taste horrible to birds.

Fun facts
It gets its name from the pipevine plant, the only food its caterpillars eat.
The caterpillars store the plant's poison in their bodies, so birds that eat them get sick.
Its eggs are red or orange and covered in bumpy stripes of food, which the babies eat when they hatch.
The caterpillars grow to about 5 centimetres long.
Its name philenor comes from a Greek word meaning fond of her husband.
