Detailed explanation-1: -Most hemipterans are phytophagous, using their sucking and piercing mouthparts to feed on plant sap. These include cicadas, leafhoppers, treehoppers, planthoppers, froghoppers, aphids, whiteflies, scale insects, and some other groups.
Detailed explanation-2: -Cicadas damage fruit trees in two ways. The most obvious damage is done during the egg-laying process. The slits made by the female in small branches severely weaken them; often the weakened branches snap off in the wind.
Detailed explanation-3: -So, what do cicada larvae look like? Technically they’re called nymphs, not larvae. When cicadas progress from one stage of development to another, they molt, rather than pupate. Each stage of development is called an instar.
