Climate Change Volunteer in Costa Rica

Video and Photos


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.

Help scientists untangle the complex relationships between caterpillars, the plants they eat, the parasitoids that eat them, and the changes in climate that will reshape the rain forest. On this expedition, you will help preserve the complex, wondrous variety of plant and animal life while working with some surprisingly fascinating creatures.
