Dear Dr. Merkler,
This is a highly variably colored Whitelined Sphinx Caterpillar, a species that is known for extreme population explosions in desert areas following winters of significantly heavy rainfall. In April, Daniel saw thousands of dark colored Whitelined Sphinx Caterpillars feeding on wildflowers in Joshua Tree National Park.
