    New research shows that the orb-weaver spider actually gets a fourth of its diet from pollen, making it more of an omnivore than a carnivore.

     A new study from a couple of European researchers has found that the orb-weaver spider consumes 25% pollen.  They were even found to eat pollen when insect prey was readily available.  Their web not only captures hapless prey, but pollen as well.  A field and lab study, including a stable isotope analysis, showed that these spiders feed on pollen and insects for optimal nutrition.  They found that the pollen eaten by these spiders are so high that they should be reclassified as omnivores instead of carnivores.
