Pea aphids extracting sap from the stem and leaves of garden peas. Nymph aphids surrounding the mother aphid were produced parthenogenetically and viviparously; sexual reproduction can be induced by shorter amounts of daylight. A study conducted by The International Aphid Genomics Consortium (e1000313) reveals significant features of the whole genome sequence of the pea aphid, shedding light on its unusual life cycle and interaction with endosymbiotic bacteria.
