  1. It looks like it is about to pop ;) What are those yellow horn-like things? Posted 6 years ago
    1. They are called 'osmeterium', and they are used to defend themselves from predators. The larvae can eject (protrude) this fleshy orange and strong smelling fork to warn predators. The smell is like a processed essence of the common ruta sp. that they feed on. Cheers* Posted 6 years ago, modified 6 years ago
