Marbled Cellar Spider

Also known as Marbled Daddy Long-Legs

Marbled cellar spiders build expansive, messy webs in dark sheltered nooks, often forming dense aggregations by joining existing webs. Distinctive dark marbling on the underside of their slender abdomen sets them apart from typical cellar spiders. Unlike most spiders, both males and females possess stridulatory organs that vibrate to produce quiet acoustic signals during courtship and territorial disputes.
