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.

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 ...

The disease hit American beech first, but it’s now widespread in the European cultivars. Rhode Island plant scientist Heather Faubert walks through acres of sick beech trees in Middletown.
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.
