It’s a dangerous world out there, especially if you are a small insect. Insects have thrived on our planet for hundreds of millions of years, so they must be doing something right despite all the threats to their survival. With so many predators out to get them many animals have evolved chemical defences, making themselves distasteful or even toxic. Wood tiger moths protect themselves from multiple predators using different chemical defences. Choosing the right defence can be tricky as predators come in many forms, and from many directions.
