Crossopriza lyoni
Tailed Cellar Spider, Tailed Daddy Longlegs Spider, Box Spider
Crossopriza lyoni is a cosmopolitan cellar spider (Pholcidae) characterized by extremely long, fragile legs and a distinctive box-shaped abdomen. Females reach 3–7 mm in body length, males 2.5–6 mm, with leg spans up to 6 cm. The species is synanthropic, thriving in human dwellings worldwide, particularly in tropical to subtropical regions. It constructs extensive, irregular cobweb-like webs and is often regarded as both a household pest and beneficial predator of mosquitoes and other arthropods. Native range unknown; now pantropical through human-mediated introduction.
