Researchers from several South American institutions have identified a new species of crevice weaver spider, expanding what scientists know about the Pikelinia genus. The species, named Pikelinia floydmuraria, pays tribute to the legendary band Pink Floyd while also reflecting where the spider lives. The name "muraria," derived from the Latin word for "wall," highlights its tendency to inhabit building walls and subtly references the band's famous album The Wall. The findings were published in the open-access journal Zoosytematics and Evolution.
Although P. floydmuraria measures just 3 to 4 millimeters in length, it may play an important role in controlling pests in urban settings. These synanthropic (urban-dwelling) spiders were found to feed mainly on Hymenoptera (such as ants), Diptera (flies and mosquitoes), and Coleoptera (beetles), based on dietary studies of both the new species and a related Pikelinia population in Armenia, Colombia.
Scientists observed these spiders capturing ants up to six times larger than their own prosoma (body) size, demonstrating an impressive ability for such a small predator. They also consistently target common household pests, including mosquitoes (Culicidae) and houseflies (Muscidae). By placing their webs near artificial light sources, the spiders appear to take advantage of phototactic (light-attracted) insects, making their hunting more efficient and potentially helping maintain balance in urban environments.
