Investigate the relationship between caterpillars and climate change on this incredible expedition!

The jungles of Costa Rica await!

On this Earthwatch expedition, you will conduct research with our scientists in searching the forests of Costa Rica for caterpillars, taking 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!

On this expedition, you will help preserve the complex, wondrous variety of plant and animal life while working with some surprisingly fascinating creatures.

When you're not working with caterpillars, you'll have almost two days of recreational time. Experience exciting touring options or just relax at the field station.

During most late afternoons, relax, socialize, and enjoy the forest sights, and end your days with dinner and planning for the following day’s fieldwork.
