Hunting Strategy

"Hunting in packs"

Most spiders aren’t just loners. They also see each other as enemies. If two spiders cross paths, it can often result in a fight to the death. But one spider proves that they can live together with others without fighting. It’s the theridion nigroannulatum, from Ecuador.


These mini spiders form colonies with several thousand members. They hang out under large leaves and let web silk dangle down on the ground. If an insect stumbles into one of these almost invisible trip wires, dozens of spiders pounce. They wrap up their victim and drag it away to share with the colony.
