Fireflies glow to attract mates. As new research shows, however, a certain species of spider has learned to take advantage of this luminous natural phenomenon. In a Journal of Animal Ecology paper published August 27, ecologists report that the sheetweb spider (Psechrus clavis) appears to exploit firefly luminescence to attract more prey. Observational analysis and lab experiments revealed that, by …

Nocturnal spiders have been filmed capturing fireflies and keeping them in their webs to attract more prey, even intermittently checking on them over the course of an hour, according to a new study. When fireflies were kept on the webs, sheet web spiders attracted significantly more prey than without the bioluminescent beetles, leading researchers to think the spiders are purposefully …

A mysterious fungus is turning spiders into real-life ‘zombies,’ consuming their organs and taking control of their behavior. Known as Gibellula attenboroughii, the fungus attaches to the spider, invades its body and devours it from the inside out. It then manipulates the spider’s brain chemistry, altering dopamine levels to force the insect out of its web and into the open, …

A fascinating study published in Proceedings of the National Academy of Sciences (PNAS) reveals a groundbreaking discovery about the feeding behavior of sea spiders in methane-rich ecosystems off the coast of Southern California. Marine biologist Shana Goffredi and her team have uncovered a new survival strategy that enables these tiny, translucent arachnids, identified as Sericosura, to thrive in one of …

A dull stretch of silty seafloor off Southern California hides a surprise that would fit on a pencil eraser. Here, three new sea spiders in the genus Sericosura have learned to live on the greenhouse gas methane, thanks to a cloak of bacteria that carpets their limbs. The work comes from marine biologist Shana Goffredi at Occidental College, whose team …

Now it seems these crawlers were swimming in good ole waters before adapting to land and engaging in a never-ending game of I-spy with humans.According to the analysis of an “exquisitely preserved” fossil that existed 500 million …

The special brains of spiders may have started to evolve in the oceans, long before their ancestors crawled onto land. A fresh look at a 500-million-year-old fossil by researchers from the University of Arizona and Lycoming College in the US and King’s College London has revealed remarkable similarities between the brains of extinct marine arthropods and modern-day arachnids. The discovery …

Technically speaking, every living thing on Earth can trace its origins to the sea. Some of these earliest creatures crawled onto land, evolving to become many different kinds of animals and insects—including, scientists believed for a long time, spiders and their relatives.  A new study published today in Current Biology challenges the popular conception that spiders first emerged on land, …
