When prey falls into their web, … Read more

Spiders Use Electric Fields to Fly, And We May Finally Know How

Having never evolved wings, many species of spider instead evolved an uncanny ability to take to the skies using nothing more than a few short threads of gossamer dangling from their dainty butts.   Just how this invertebrate answer to paragliding works has never been entirely clear, though historically biologists have assumed it probably has … Read more

Millions of Palm-Sized, Flying Spiders Could Invade the East Coast

New research, published Feb. 17 in the journal Physiological Entomology, suggests that the palm-sized Joro spider, which swarmed North Georgia by the millions last September, has a special resilience to the cold. This has led scientists to suggest that the 3-inch (7.6 centimeters) bright-yellow-striped spiders — whose hatchlings disperse by fashioning web parachutes to fly … Read more

The bug-like Cambrian creatures could help scientists piece together the evolutionary history of modern-day spiders and scorpions.    Still, it’s not clear exactly where these fossils – both specimens of the species Mollisonia symmetrica – fit on the arthropod … Read more

This Adorable Jumping Spider Can’t Actually See Its Own Most Vivid Color

Jumping spiders may have exceptional eyes, but one adorable species seems to have a curious lack in the vision department. New experimental evidence suggests that a jumping spider called Saitis barbipes has no photoreceptors capable of perceiving the color red.   What makes this so strange is that S. barbipes – like many jumping spiders … Read more
