turning bridge

A swing-bridge (q. v.). turning-carrier, s. [CARRIER, 8., II. 3 (1).] powers, but is really a very small beetle, with long and strong hind legs and ample shining black wings, with two yellowish stripes down the wing cases, and ocherous legs. It commits great ravages in turnip-fields by devouring the seed-leaves as soon as they appear above ground. The female lays her eggs on the under-side of the leaf, in which the larva mines, and makes a tortuous gallery. turnip-fly, 8. Entom.: A popular name for two insects which are quite distinct, and belong to different orders, but are both destructive to turnips. (1) Athalia cen tifolia , a hymenopterous insect, the larva of which is known by the popular name of "nigger," on account of its black color; (2) Anthomyia radicum , a two-winged fly of the family Muscide. The larvæ live upon the roots of the turnip, often doing great damage. turnip-jack, 8. [TURNIP-FLEA.] turnip-moth, s. Entom.: A night-moth, Agrotis segetum , the caterpillar of which feeds on the interior of turnips. The eggs are laid in June on or near the ground. The caterpillar, when hatched, attacks not merely turnips, but other culinary vegetables, such as carrots, cabbage-plants, mangel wurzel, radishes, and many other plants. It also eats garden flowers, as the China Aster. The mature insect has the antenne strongly ciliated in the mare, simple in the female; the fore wings are nearly square, in color pale gray-brown in the male, darker in the female, the hind wings with spots and shades of brown. turnip-radish, s . Bot .: A variety of Raphanus sativus. [RADISH, RAPHANUS.] turnip saw-fly, s. Entom.: Athalia spinarum , about a quarter of an inch long, of a reddish-yellow color. The larvæ feed on leaves of turnips and other cruciferous plants, to which they do great damage. turnip-shaped, a. Bot .: Having the figure of a depre ed sphere; napiform.
