hostplants

Apocynaceae, oligophagous

Asclepias curassavica, physocarpus, tuberosa; Calotropis procera; Gomphocarpus fruticosus; Nerium oleander; Vinca; Vincetoxum.

In the Mediterranean region very common on oleander. In small numbers the aphds may also be found on plants of other families.

synonyms

Cerosipha, Myzus, nerii.

notes

Asclepiadaceae contain many toxic compunds, and part of them are ingested by the aphids (Rothschild ao). The strikingly bright colouration of the aphids therefore is interpreted as aposematic (Malcolm).
