Lifecycle

Female aphids lay live young, a process known as viviparity. Female aphids reproduce by parthenogenesis, males have never been observed in the wild but have been produced under laboratory conditions. Females may be wingless or winged, the production of the alate form occurs a higher rate in those regions where it is necessary for oleander aphid to migrate each year on to temporary hosts.
Oleander aphid has a wide range of hosts, but mainly feeds on plants in the dogbane family, including milkweeds, oleander and periwinkle. It is occasionally recorded feeding on plants in the bindweed family, daisy family and spurge family as well as rarely being recorded on Citrus.
