There is no egg stage. Young are born live. Like most other aphid species, the banana aphid has four nymphal stages. Newborn nymphs are oval at first and become slightly elongated. They have six-segmented antennae that are as long as the body.
Adults start producing young one day after reaching maturity.
They can give birth to 4 aphids per day with an average production of 14 offspring per female. The entire inflorescence may be infested. Small colonies occasionally occur on the leaf blade. Ants are associated with the banana aphid. The ants feed on the honeydew secreted by the aphid and, in turn, establish new aphid colonies and ward off natural enemies.
