Archive image from page 239 of The anatomy, physiology, morphology and. The anatomy, physiology, morphology and development of the blow-fly (Calliphora erythrocephala.) A study in the comparative anatomy and morphology of insects; with plates and illustrations executed directly from the drawings of the author; CUbiodiversity4765349-9885 Year: 1890 ( 204 THE INTEGUMENTAL SKELETON OF THE IMAGO. the wing apex; o represents the thoracic attachment of the remigium and the radiating Hnes represent the successive positions of the anterior margin of the wing, seen in per- spective. Starting from the point h on the curve, the wing plane is approximately vertical, the dorsal surfaces of the two wings turned towards each other, and the apex of the wing in front of the wing-root. In passing from h to a, the anterior borders of the two wings are nearer each other than the posterior borders, so that the insect is driven forwards by the backward movement of the wings. Fig. 36.—a Curve showing the loci of a point at the tip of the wing during flight, seen from below the horizontal plane passing through the wing-roots. During the descent of the wing from a to h, the plane of the wing is at right angles to its movement, so that the insect is borne upwards, and at h the wings lie in the horizontal plane. From 6 to c the wing slopes so that its plane corresponds with the plane of movement, the front edge of the wing cutting the air. The movement of the wing in the plane oh od is due to the combined swing of the propterygium on the axis of the dens, and the extension of the propterygium.
