 A test in 2001 showed that four jumping species take nectar , either by sucking it from the surface of flowers or biting the flowers with their fangs . The spiders fed in cycles of two to four minutes , then groomed , especially their chelicerae , before another cycle . A more formal part of the test showed that 90 juvenile jumping spiders , including P. labiata , generally prefer to suck from blotting soaked with a 30 % solution of sugar in water rather than paper soaked with pure water . The authors suggest that , in the wild , nectar may be a frequent , convenient way to get some nutrients , as it would avoid the work , risks and costs ( such as making venom ) . Jumping spiders can benefit from amino acids , lipids , vitamins and minerals normally found in nectar .
