Leaves show a characteristic curling, similar to damage caused by viruses. Heavily infested plants have shortened internodes leading to resetting or a "bunchy top" appearance. A heavy, black, sooty mold may develop on an infested plant's leaves and stems as a result of the mealybug's heavy honey-dew secretions.

Leafhoppers mainly are herbivores, but some are known to eat smaller insects, such as aphids, on occasion. A few species are known to be mud-puddling, but as it seems, females rarely engage in such behavior. Many species are also known to opportunistically pierce the human skin and draw blood but the function of such behaviour is unclear.

The leaf edges are generally entire, though sometimes finely serrated. The leaves are dull blue-green in color and smooth in texture when mature; new leaves are coated in downy hairs. The leaves are up to 5 in long and 1.5 in wide. Like other willows, this plant is dioecious, with male and female plants producing small, dangling catkins.
This tree is mostly deciduous during the winter, but can start growing back leaves early during warm snaps in the winter. Yellow flowers grow in drooping catkins. In female red willows, the catkins turn into tufts of cottony seeds, which are windborn, often in large quantities, for 2-3 weeks in the spring. [ 4 ]
