Dysderidae
spider family
Quick Summary
The family Dysderidae, also known as woodlouse spiders, comprises about 500 species found worldwide. These spiders are characterized by having four spiracles, which are openings for their respiratory tracheae, arranged in two pairs, one behind the other. Unlike many other spider families, Dysderidae do not build webs to catch prey. Instead, they are active hunters, often found in dark, damp environments like under rocks, logs, or in cellars, where they hunt woodlice and other small invertebrates.1
