Do you have any facts about greenflies?

Greenflies, commonly known as aphids, are small sap-sucking insects that belong to the family Aphididae. They are often green but can also be found in various colors, including black and brown. Greenflies reproduce rapidly, with some species able to give birth to live young without mating, leading to population explosions. They are known to damage plants by feeding on their sap and can also transmit plant viruses, making them significant pests in agriculture and gardening.
