Aphides

n. insect which sucks sap from plants

"Aphid" is also the NATO reporting name for the Soviet/Russian Molniya R-60 air-to-air missile. Aphids, also known as greenfly, blackfly or plant lice, are minute plant-feeding insects in the superfamily Aphidoidea in the homopterous division of the order Hemiptera. Recent classification within the Hemiptera has changed the old term 'Homoptera' to two suborders: Sternorrhyncha (aphids, whiteflies, scales, psyllids...) and Auchenorrhyncha (cicadas, leafhoppers, treehoppers, planthoppers...) with the suborder Heteroptera containing a large group of insects known as the 'true-bugs'; gnat bugs, pond skaters, shore bugs, toad bugs, water boatmen, backswimmers, etc. More recent reclassifications have resulted in a substantial rearrangement of the constituent families with the Aphidoidea, with some old families reduced to subfamily rank (e.g., Eriosomatidae), and numerous old subfamilies elevated to family rank.
