Only one percent of all caterpillars are carnivorous and generally feed upon soft flesh of insects. Some of them begin their life by eating plants of a specific type, but as they grow they switch to certain types of insects. The most interesting thing about them is the way they kill in order to arrange for food. They use seductive smells or camouflage in order to trap their prey. However, this kind of caterpillars are very hard to find.
