Question: are aphids the same as greenfly?
Answer: Aphids are sap-sucking true bugs. ... Some aphids are known as greenfly or blackfly, but there are species that are yellow, pink, white or mottled. Some species, like woolly beech aphid and woolly aphid on apple, cover themselves with a white waxy secretion and can be confused with some scale insects, mealybug or whitefly.
