Cellar spider (likely a short-bodied cellar spider)

Dark, sheltered places such as garages, basements, and spaces beneath eaves; the image shows a spider hanging below a dense egg-sac cluster.

Catches small insects and other spiders in irregular webs.

Females carry a cluster of eggs in their jaws or hold it within a loose web; spiderlings disperse after hatching. Identification from the photo is uncertain, and the egg cluster may belong to another spider nearby.

Harmless to people and useful for controlling small household pests.
