Say this for spiders: they know how to hoard food particularly the newly discovered Darwin's bark spider, discovered in Madagascar. The most prodigious web-spinner of any known arachnid, the bark spider produces silk thought to be 100% tougher than any studied before. Good silk means good webs, and scientists found one example that stretched 25 m (82 ft.) across a Madagascar river. At least 30 insects were found trapped in the threads, meaning leisurely dining for the spider and more food arriving all the time.
