aphids in large dense groups on the young shoots and along the midrib of the leaves. Aphids 2-3 mm, bright lemon yellow with dark antennae and feet, and black siphunculi and cauda.
In the Mediterranean region very common on oleander. In small numbers the aphds may also be found on plants of other families.
Cerosipha, Myzus, nerii.
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).
