Arachnid · GBIF taxon 2150555
Short-bodied Cellar Spider
Physocyclus globosusAlso known as Globe Cellar Spider, Short Cellar Spider
Short-bodied cellar spiders hang upside down in loose, irregular webs tucked into dark corners of buildings, caves, and sheltered structures worldwide. When threatened, they bounce violently in their webs to turn into a blurry motion that confuses potential predators. Their rounded, globe-like abdomens and compact body shapes distinguish them from their longer-bodied pholcid relatives.
