 A test in 2001 showed that four jumping species take nectar , either by sucking free nectar from the surface of flowers or biting the flowers with their fangs . The spiders fed in cycles of two to four minutes , then groomed their bodies and especially their chelicerae , before another cycle . A more formal part of the test showed that 90 juvenile jumping spiders , including P. fimbriata , generally prefer to suck from blotting soaked with a 30 % solution of sugar rather than paper soaked with distilled 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 ) of predation . Jumping spiders may benefit from amino acids , lipids , vitamins and minerals normally found in nectar .
