In an effort to increase awareness of the 'lesser-studied' terrestrial arthropods, here is a repository for all sightings of Arachnids (spiders, scorpions, harvestmen, vinegaroons, etc.) and Myriapods (Centipedes, Millipedes, and allies) in North America (Mexico included).

Please limit observations to the Arachnida and Myriapoda (Chilopoda, Diplopoda, Pauropoda, or Symphyla).
This is not a place for insects, crustaceans, earthworms, or molluscs. As a general rule of thumb, if it has more than 8 legs, it's a go!

What is the purpose of this project? Simply to learn more about the distribution and biology of secretive, obscure, bizarre, and poorly known groups of invertebrates. less ↑
