    • n Aphis (Zoöl) A genus of insects belonging to the order Hemiptera and family Aphidæ, including numerous species known as plant lice and green flies.☞ Besides the true males and females, there is a race of wingless asexual individuals which have the power of producing living young in rapid succession, and these in turn may produce others of the same kind for several generations, before sexual individuals appear. They suck the sap of plants by means of a tubular proboscis, and owing to the wonderful rapidity of their reproduction become very destructive to vegetation. Many of the Aphidæ excrete honeydew from two tubes near the end of the body.

    • n aphis A genus of small plant-sucking insects, of the family Aphididœ and order Homoptera. They multiply by parthenogenesis and very rapidly. From a pair of honey-tubes, near the end of the abdomen, they emit a saccharine fluid, known as honey-dew and aphis-sugar, which is greedily devoured by ants. They are very destructive to tender plants, upon which they congregate in enormous numbers.
    • n aphis [lowercase] A plant-louse. [In this sense the plural aphides (af'i-dēz) is used.]
