Showing 17 types of SPIDERS

Barn Funnel Weaver

Latin Name: Tegenaria domestica

Possibly European in origin, but current thought is that it may be native to Canada and has spread south from there. It now is found throughout much of the U.S. and southern Canada as well as all of Europe.

Black Widow Spiders

Latin Name: Latrodectus mactans, L. hesperus

Latin Family Name: Theridiidae

Five species of these native spiders occur in North America, being found in all states and in southern Canada. Other species may be found worldwide.

Brown Recluse Spider

Latin Name: Loxosceles reclusa

Latin Family Name: Loxoscelidae

There are 11 species of Loxosceles that are native to the United States, and at least one imported species that is found in the southwest. The Brown Recluse, L. reclusa, has the widest range, from a small area of western Florida to Texas and north to Iowa. It has been found sporadically as a transient in other states. The other 10 native species are found in the southwest from Texas to California.

Brown Widow Spider

Latin Name: Latrodectus geometricus

The actual origin of this species is uncertain, as it was first discovered in South America, but believed to have originated in Africa. It was found in Florida in the mid-20th century and remained restricted to that state until around 2000 when it began to be found in other states from Texas to South Carolina and in 2003 showed up in southern California. Since that time it has spread rapidly throughout southern California and is thought to even be displacing the black widows there.

Cellar Spiders

Latin Name: Pholcidae

Latin Family Name: Pholcidae

Several dozen species of Pholcids are native to North America, with the three species listed above the most common to be found in and on structures.

Chilean Recluse Spider

Latin Name: Loxosceles laeta

This species is native to much of South America, but commonly hitchhikes on exported materials. It has been found in several Central America countries, in Finland, and in scattered states in the U.S., including California, Florida, Massachusetts, and Kansas. It does not appear currently to be a breeding resident in North America.

Desert Recluse Spider

Latin Name: Loxosceles deserta

This is a native species in the southwest U.S.

Giant House Spider

Latin Name: Tegenaria gigantea

This species currently is believed to be native to Europe but was first discovered in North America in 1929, reaching Seattle in 1960.

Ground Spiders

Latin Name: Gnaphosa sp.

These are primarily native species in North America.

Hobo Spider

Latin Name: Tegenaria agrestis

Latin Family Name: Agelenidae

Like the Domestic house spider this species was believed to be native to Europe, but new evidence suggests that it has long been a native of western Canada and now has moved into the Pacific Northwest of the U.S. as well, where it is common in and around homes. It appears to be moving eastward and now can be found in Colorado, Montana, and Wyoming and west to the Pacific Coast of Oregon, Washington, and British Columbia.

Parson Spider

Latin Name: Herpyllus ecclesiasticus

Latin Family Name: Gnaphosidae

Native to North America, and found throughout the United States.
