The beech blight aphid (Grylloprociphilus imbricator) is a small insect in the order Hemiptera that feed primarily on the sap of American beech trees. The aphids form dense colonies on small branches and the undersides of leaves.
Scorias spongiosa is a specialist and grows exclusively on the honeydew formed by colonies of the beech blight aphid, Grylloprociphilus imbricator.This aphid is found only on one host plant, the American beech tree, Fagus grandifolia, where it congregates on branches and twigs, creating copious amounts of honeydew that drip onto vegetation below.

In general the aphid carrying capacity of annual crop plants tends to increase with the season until the plants mature after which it tends to decrease very rapidly. Thus, the aphid carrying capacity of trees tends to be high in spring and autumn and low in summer, whereas that particularly of short-season annual crops tends to be low early in ...
Two of my favorite spring plants, almost entirely based upon their progression from bud to leaf, are beech trees and false hellebore. Two of my favorite spring plants, almost entirely based upon ...
Hemiptera (/ h ɛ ˈ m ɪ p t ər ə /; from Ancient Greek hemipterus 'half-winged') is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs.
The removal of sap creates a lack of vigor in the plant, and aphid saliva is toxic to plants. Aphids frequently transmit plant viruses to their hosts, such as to potatoes, cereals, sugarbeets, and citrus plants. [29] There are two types of virus transmission between plant-aphid interactions: non-circulative transmission and circulative ...
Mealybug females feed on plant sap, normally in roots or other crevices, and in a few cases the bottoms of stored fruit. They attach themselves to the plant and secrete a powdery wax layer (hence the name "mealy" bug) used for protection while they suck the plant juices. The males are short-lived, as they do not feed at all as adults and only ...
Hemimetabolism or hemimetaboly, also called partial metamorphosis and paurometabolism, [1] is the mode of development of certain insects that includes three distinct stages: the egg, nymph, and the adult stage, or imago. These groups go through gradual changes; there is no pupal stage.
