Desert Tarantula (Aphonopelma chalcodes)

General: Spiders are a diverse group of hugely abundant animals in the desert around Las Vegas. Spiders are recognized from other invertebrates by their eight legs, two body segments, and spinnerets (which produce the silken material they use to spin webs). Spiders do not have wings or antennae.

Most spiders are small and harmless, others are big and harmless, and a few are medium and harmful.

There are far too many species of spiders in the Mojave Desert to list them all. The intent here is to list a few of the common, conspicuous, and interesting species. While this website celebrates the lives of wild creatures, they do belong out doors. For people who have trouble with spiders in the home, consider contacting Fischer's Pest Control.
