Researchers have identified what may be the largest spiderweb on Earth — a vast colony of more than 111,000 spiders thriving in total darkness within a cave along the Albanian-Greek border.
According to a study published on October 17 in Subterranean Biology, the “extraordinary” structure occupies 1,140 square feet (106 square meters) of wall surface in a narrow, low-ceilinged passage near the cave’s entrance. The colossal web is formed by thousands of interconnected, funnel-shaped webs, creating a dense, seamless network.
This is the first documented case of colonial behaviour between two common spider species — and possibly the largest spiderweb ever recorded — said lead author István Urák, associate professor of biology at Sapientia Hungarian University of Transylvania in Romania.
"The natural world still holds countless surprises for us," Urák told Live Science. "If I were to attempt to put into words all the emotions that surged through me [when I saw the web], I would highlight admiration, respect, and gratitude. You have to experience it to truly know what it feels like."
The massive web was found inside Sulfur Cave, a cavern formed by sulfuric acid created from the oxidation of hydrogen sulfide in groundwater. The structure was first spotted in 2022 by cavers from the Czech Speleological Society during an expedition to the Vromoner Canyon. In 2024, a team of scientists collected samples from the site, which Urák later analysed before leading his own expedition to the cave.
The research identified two species living in the colony — Tegenaria domestica (the barn funnel weaver or domestic house spider) and Prinerigone vagans. Urák and his team estimated there were roughly 69,000 T. domestica and more than 42,000 P. vagans individuals. DNA analyses confirmed these two species dominate the population.
Sulfur Cave’s spider community stands out as one of the largest ever observed. *** Local Ca
