On sunny days you can see these little black and white striped arachnids running about on walls and fences in search of prey. Zebra spiders catch their food by literally jumping on it, and if there was an Olympic event for spider long jump these guys would be gold medalists. They can jump more than 20 times their own body length!
They also have incredibly good eyesight and if you put your face close to them they raise up on their front legs to get a better look at you. They'll sometimes even let you feed them. Just pick up a greenfly by its wings with a pair of tweezers or forceps, hold it near the spider and watch it jump to it.
