Though fold lines may be transverse, as in the hind wings of beetles and earwigs, they are normally radial to the base of the wing, allowing adjacent sections of a wing to be folded over or under each other.
Shortly after the alates land, they shed their wings, leaving only the base of the wing scale attached to the thorax.
It was also shown that the LEV, which is generated near the base of the wing, is reliant upon the geometry of the wing, Reynolds number, and angle of attack (Lentink et al. 2009).
They found that as the fly veered to one side, a small flap at the base of one wing would flip out on that side, while the flap on the other wing remained flat (see video).
The concave surface of the dimer contains extensive positive charge, particularly in the domain's bent wings, and an additional positively charged patch was present near the base of each wing in the dimeric core.
Wing disks develop in association with a trachea that runs along the base of the wing, and are surrounded by a thin peripodial membrane, which is linked to the outer epidermis of the larva by a tiny duct.
The chief flight muscles control flight in one of two ways: in dragonflies, directly on a lever at the base of each wing; but, in most insects, indirectly by deforming the shape of the thorax.
The primary forking of the takes place near the base of the wing, forming the two principal branches (Cu1, Cu2).
In direct muscle, the connection is directly from the pleuron (thoracic wall) to individual sclerites located at the base of the wing.
Characteristic of the wing base is also a small lobe on the anterior margin of the articular area proximal to the humeral plate, which, in the forewing of some insects, is developed into a large, flat, scale-like flap, the tegula, overlapping the base of the wing.
