What feeding specialization defines the Order Hemiptera to which *A. nerii* belongs?
Answer
Possessing piercing-sucking mouthparts to extract plant fluids
The placement of *Aphis nerii* into the Order Hemiptera signifies a fundamental characteristic common to all members of this order: the presence of specialized piercing-sucking mouthparts. These mouthparts are modified structures that function like a rigid stylet bundle, allowing the insect to penetrate plant tissues. Once inside the vascular system or parenchymal cells, the aphid can effectively suck out the nutrient-rich plant sap. This feeding mechanism is essential for the aphid's survival, distinguishing them from insects that chew plant material or lap up liquids.
