📖 1. Overview

The long-bodied cellar spider is a long-legged spider that hangs upside down on ceilings and in corners of homes, preying on other spiders and small insects.

🦴 2. Anatomy & Morphology

Its body is pale yellowish brown with a large gray patch in the center of the cephalothorax, and both its body and legs are nearly translucent. Under a microscope, blood cells can be seen moving inside the legs and body of a living individual.

🔍 3. Ecology & Behavior

It spins a large, loose, flat horizontal web and hangs upside down beneath it. It kills and eats other spiders and small insects with venom, and sometimes invades and takes over the webs of other spiders.
