Arthropod identification tools are usually designed for scientists microscopically examining specimens, and often unavailable to the public. At the same time, there are startlingly few resources available to understand the classification of arthropod groups from a birds-eye view, and those that exist tend to be geographically limited or poorly explained. This guide intends to provide thorough resources for naturalists to identify arthropods anywhere in the world.
