A female jumping spider Maevia inclemens drinks nectar from a shrub in South Carolina. Jumping spiders can be identified by their large pair of eyes, flanked by three smaller pairs.

A male jumping spider (Hentzia mitrata) drinks nectar from a shrub nectary. Researchers aren't sure how important plant foods are to a spider's overall diet, but having diverse food options probably helps spiders to survive when insect prey is scarce, researcher Martin Nyffeler and colleagues wrote in a review in The Journal of Arachnology.

Searching for nectar

A male jumping spider (top) and a female jumping spider (bottom) eat nectar from a shrub in South Carolina. Both spiders are of the species Pelegrina galathea. Jumping spiders actively wander over plants and seek out nectaries, which are full of energy-rich, sugary liquid.

A Sassacus papenhoei jumping spider with a jewel-like abdomen feeds on nectar in South Carolina. Jumping spiders represent about 60 percent of reported incidents of plant-eating, but other groups such as nocturnal running spiders have been seen feeding on plant products, too. More study is needed to understand how spiders incorporate plants in their diet, researchers wrote in The Journal of Arachnology.
