Join the adventurous journey of a caterpillar! This film follows the life of a caterpillar. But this seemingly ordinary caterpillar experiences many exciting and spectacular adventures before it can become a butterfly. The film tells a story that we as a laboratory conduct a great deal of research on: how and why a caterpillar selects its favourite host plant, how a caterpillar grows, and which natural enemies prevent caterpillar infestations from occurring. A celebration of biodiversity on the big screen.
