Cellar spider (daddy-longlegs spider)

Common indoors in quiet, sheltered corners, basements, and cellars; also occurs in caves and other protected places.

Catches flies, mosquitoes, and other small arthropods in a loose, irregular web; may also prey on other spiders.

Hangs upside down in its web and rapidly vibrates when disturbed. Females carry a small cluster of eggs in their jaws and guard the young.

Harmless to people and pets; its bite is rare and not medically significant. It helps control household insects and spiders.
