Staten Island X, 31 (Ds); Anglesea V, 28 (Sm); common, the imago frequently met with in winter on pine trees (Sz). Family APHIDID^. The "plant-lice," "green-flies" or "aphids" are among the commonest and most abundant of all our insects, and also among the most destructive. They have, when winged, two pairs of transparent wings, the anterior much the larger; but some species and some forms of nearly all species never develop wings at all. The bodies are plump, oval, with usually a pair of "honey tubes" or "cornicles" near the anal end, a pair of long antennae and rather long sprawly legs. They frequently cluster in great numbers about twigs or shoots of plants or on the under surface of leaves, sucking the juices and excreting from the anal end a thin sugary liquid, the honey dew. This honey dew when present in quantity tends to choke the leaves upon which it falls, and that tendency is furthered by a black soot fungus which develops on the honey dew and disfigures and some- times checks the growth of fruits as well as Fig. 43.—Wheat plant louse; much enlarged. The life history of the species is interesting and sometimes compli- cated; but briefly stated is generally about as follows: They winter as.
