Range
native to the Mediterranean, now cosmopolitan
Habitat
Fields, gardens
Season
Summer
Food
Feed on the sap of plants in the dogbane family, Apocynaceae, including milkweeds (formerly in their own family, the Asclepiadaceae). Best-known hosts: Oleander, Milkweed, and Vinca. Also feed on Crassulaceae and Solanaceae.
Life Cycle
NA populations are parthenogenetic (reproduce without males)
Remarks
Like the Monarch and related butterflies, these aphids pick up deadly cardiac glucosides from the host plant and deposit them in their bodies. The noxious chemicals also become part of their cornicle secretions (exuded from the tubes on the rear end). Their bright orange color serves as a warning to predators- at best they taste awful, at worst they can kill.

Larvae of lacewings and lady beetles that feed on Aphis nerii may have developmental problems during pupation, and either emerge with deformities (especially of the wings), or fail to emerge at all.
