There is always a new and exciting discover in the insect world!

In Hawaii’s freshwater streams, 14 new species of amphibious caterpillars have been found. While many insect larvae live in streams and lakes, these are the first truly amphibious insects (they are equally at home in water or on land) that have ever been discovered, anywhere in the world.

It is still not understood how the caterpillars, which grow to be small moths, can breathe under water. A clue may be that they only live in fast-moving streams. The water in these streams have high oxygen levels, so somehow they may be absorbing oxygen by a process not yet understood.
