Long-legged fly

Common in dark, sheltered indoor spaces such as basements, corners, and garages.

Predatory; feeds on flies, mosquitoes, and other small arthropods, sometimes including other spiders.

Builds loose, irregular webs and may vibrate rapidly in the web when disturbed. Females carry egg clusters in their jaws.

Harmless to people and useful for controlling household insect pests. The image is too small for confident species-level identification.
