Critters from the scientific classification order Arthropoda are the least documented in the park, even though they can be seen everywhere. These species lists are extremely incomplete, with the future hope of documenting thousands of different creatures with wings and/or multiple pairs of legs.
Go to the National Park Service IRMA Portal NPSpecies site to see a working list of insects, spiders, centipedes and millipedes in the park.
Scientific classification abides by the following hierarchy:
Kingdom, Phylum, Class, Order, Family, Genus, Species
Insects, spiders, centipedes and millipedes all belong to the kingdom Animalia and the phylum Arthropoda. However, they diverge as you move farther down the scientific classification chain. These four groups are part of different classes:
An example of an unofficial insect species list from the order Plecoptera is found below. It was compiled from unpublished reports over several years and updated by park volunteer Dr. Burt Cushing and other sources. We are very grateful for all their assistance.
This list is incomplete, but it gives you a taste of the sheer number of species found within one order of the class Insecta. Imagine how these numbers can grow exponentially when all species from other orders can be included.
