Although aphids cannot fly for most of their life cycle, they can escape predators and accidental ingestion by herbivores by dropping off the plant onto the ground. [103] Others species use the soil as a permanent protection, feeding on the vascular systems of roots and remaining underground all their lives.
Honeydew is a sugar-rich sticky liquid, secreted by aphids, some scale insects, and many other true bugs and some other insects as they feed on plant sap. When their mouthpart penetrates the phloem , the sugary, high-pressure liquid is forced out of the anus of the insects, allowing them to rapidly process the large volume of sap required to ...
After mating, females lay 10 to 16 winter eggs on the host plant. In Central Europe, preferred host plants are Fagus sylvatica, in Turkey Fagus orientalis, in North America Fagus sylvatica and Fagus grandiflora. [6] These insects can be found primarily on the foliage. [7] These aphids are a serious pest in European beech forests.
