Wicked Bugs (and Spiders and Worms and Other Creepy Crawlies)

Sure, they do plenty of good---such as keeping their naughty brethren in check, contributing to the world of medicine, providing key roles in the food webs that are essential to healthy ecosystems---but we can't help but focus on the bad.

North American Bumblebees on the Decline
"The bees are disappearing." It's such a well-known fact that it even became a key plot point in season 4 of Doctor Who (with the explanation that the bees were aliens simply returning to their home planet). Most of the concern has centered on honeybees and the problem now known as colony collapse ...

Dryer Sheets as Bug Repellant?
It's a modern old-wives tale: put a Bounce dryer sheet in your pocket while gardening and it'll keep away the mosquitoes or gnats.

Gargantuan Spider Webs Bridge Waters of Madagascar
As a young girl, I used to wake up in the middle of the night, frightened by a spider I knew had to be lurking in some dark corner of my room. For arachnophobes such as myself, nothing could be more unsavory than a big spider that blends seamlessly into tree bark. Unless that same spider also spins...
