They can be quite a few shades – pale yellow, environmentally friendly, orange and almost black some are even shiny purple.
There are about 1,350 aphid species in North America, with more than 5,000 globally.

But huge figures of aphids feeding on plant shoots or buds can induce leaf yellowing and curling, followed by wilting, untimely leaf browning and loss of life of shoots or buds. In evergreens, substantial aphid infestations can result in branch loss of life.
