Story summary

Researchers report the world's largest spider web in Sulfur Cave on the Greek-Albanian border, housing 110,000 spiders.
The web hosts two species, the common house spider, Tegenaria domestica, and Prinerigone vagans.
The study, published in Subterranean Biology, notes these species coexist peacefully, a behavior not previously observed.
The coexistence is attributed to the cave's abundant food from midge flies.
The cave environment also influences reproduction, with spiders laying fewer eggs.
