Like most places on Earth, Grand Canyon National Park has far more species of invertebrates than any other animal group. While these animals do not have skeletons, many (including insects and arachnids) have hard exoskeletons, and they are very abundant- 1443 species of invertebrates have been identified inside the park, and there are certainly many more species waiting to be identified. Though many people dismiss insects as "pests" or "disgusting" these creatures play important roles in the ecosystems of the Grand Canyon. Many species such as the Arizona carpenter bee and the rare Kaibab swallowtail butterfly pollinate flowering plants, while many beetles and ants decompose dead material. Predatory invertebrates feed on other invertebrate species, and all invertebrates are prey for birds, mammals, reptiles, and amphibians.

From Arizona bark scorpions (Centruroides sculpturatus) and tarantulas to Arizona's state butterfly, the two-tailed swallowtail (Papilio multicaudata), you can always find something moving if you look closely. Study and observe these tiny animals, but do not disturb or harm them.
