40 Australian Creatures You Never Thought Existed

Rhinoceros Cockroach (Macropanesthia rhinoceros)

Also known as the Giant Burrowing Cockroach, this little shop of horrors can grow to 3 ½ inches and weigh up to 35 grams. They also live for around 10 years. Luckily, unlike other cockroaches these do not have wigs and cannot fly. In fact, they live underground and aren’t really considered a pest as they are mostly confined to the back garden. Phew.

Spitfire Caterpillars (Perga affinis)

Commonly mistaken for caterpillars, these sawfly larvae huddle in clusters on tree trunks and are known to eject a strong-smelling yellow-green liquid that consists mostly of eucalyptus oil (hence the name Spit Fire) when threatened. It is most likely to cause problems for humans if this liquid gets in your eyes as it can burn.
