Deer keds rely on flight and vision to find a host, but everything changes once they land. After shedding their wings forever, these parasites reduce the activity of key vision-related genes by about half. Scientists believe they are effectively trading sharp eyesight for extra energy that can be used for feeding and reproduction.

Scientists have uncovered a tiny wall-dwelling spider named Pikelinia floydmuraria, inspired by Pink Floyd. Despite its size, it’s a fierce predator that hunts ants much larger than itself and helps reduce common urban pests like mosquitoes and flies. Its clever strategy of building webs near lights makes it especially effective. The discovery also raises new questions about its mysterious link to similar spiders in the Galápagos.

A unique hybrid honeybee thriving in Southern California may hold a powerful clue to saving struggling bee populations. While U.S. beekeepers are losing massive numbers of colonies—largely due to destructive Varroa mites—a locally adapted mix of feral and diverse bee lineages is showing remarkable resilience. These bees aren’t immune, but they carry far fewer mites and are far less likely to require chemical treatments. Even more surprising, their resistance appears to start early in […]

A newly discovered group of tarantulas is so bizarre that scientists had to invent a whole new genus—Satyrex—to describe them. With unusually long mating appendages and fierce, hissing defenses, these spiders are as strange as they are intimidating.

What started as routine fossil cleaning turned into a major scientific surprise when researchers uncovered a tiny claw in a 500-million-year-old specimen where no claw should exist. That detail revealed Megachelicerax cousteaui, the oldest known relative of spiders, pushing the origins of this group back by 20 million years. The fossil shows that key features of modern spiders and horseshoe crabs were already emerging during the Cambrian Explosion.
