Within the United States, Phidippus adumbratus is within the California Floristic Province in native chaparral and in oak-sycamore-chaparral woodland between 500–3,700 ft (150–1,130 m). [7] A spider survey published in 1999 found P. adumbratus present in coastal sage scrub in the vicinity of San Diego . [ 8 ]

Although most spiders live for at most two years, tarantulas and other mygalomorph spiders can live up to 25 years in captivity. While the venom of a few species is dangerous to humans, scientists are now researching the use of spider venom in medicine and as non-polluting pesticides.
Also worth noting: “These are nomadic spiders that don’t spin webs to catch their prey—they hunt them down,” says Howard Russell, an entomologist at Michigan State University.
Antrodiaetidae, also known as folding trapdoor spiders or folding-door spiders, is a small spider family related to atypical tarantulas. They are found almost exclusively in the western and midwestern United States, from California to Washington and east to the Appalachian Mountains . [ 1 ]
