For example, the winged adults of the orange pods are 1.2 mm in length, black in lacquer, red and black in compound eyes, gray-brown tentacles, and 2 pairs of colorless and transparent wings. And wingless adults are similar to winged adults but they do not have wings. The winged adult of the orange bifurcation is 2.5 mm in length, dark brown, and colorless and transparent. The wingless adult body is only 2 mm in length, nearly circular, with a web on the abdomen and thoracodorsal. Adults and nymphs clustered on young shoots, young leaves, and flowering young fruit to extract sap; and induced coal disease.
