Spiders forage for prey rich in specific nutrients depending on species, life stage and sex

A new field study of arachnid hunting behavior has shown that spiders forage for prey rich in specific nutrients, and their preferences depend on the individual spider's species, life stage and sex. The results suggest that it may be possible to link spider predation to pest control in famers' fields if the various arachnid species can be encouraged to selectively hunt troublesome insects.
