On this Earthwatch Expedition, you’ll search the forests of Costa Rica for caterpillars and take specimens to the lab for state-of-the-art chemical analysis and observation. Prepare to be dazzled by the array of shapes and colors that caterpillars come in, most of which serve as natural defenses against their predators. You may even find a new species—it’s happened before.
