    • n nervure In botany, a vein or nerve of a leaf.
    • n nervure In entomology, one of the tubes or tubular thickenings which ramify in an insect's wing: a nerve, vein, or costa proceeding along one of certain definite lines, to strengthen the wing and, through a central hollow, to nourish it. The wing is developed as a saclike projection of the body-wall, and is hence composed of two closely applied membranes. The nervures are exactly apposed thickenings of the dorsal and ventral membranes. In most insects a groove extends along the inner surface of the thickening of each wall, forming a tube in the center of each nervure within which the fluids of the body circulate. The larger ones also contain tracheæ. The number of these nervures is greatest and their arrangement is most complicated in some of the Orthoptera and Neuroptera, while they are almost entirely wanting in some of the small Hymenoptera. The nervures furnish important zoölogical characters. See cut in preceding column.
