Insect Wing Venation Diagram

On the right side of the diagram there is a section across the wing.

Insect wing venation diagram. Diagram of insect wing venation. Since all winged insects are believed to have evolved from a common ancestor the archediction represents the template that has been modified and streamlined by natural selection for 200 million. 2014 this order level representation of insect wing venation patterns shapes and vein domains as defined in the figure on the right exhibits the range and diversity of our sampling insect orders labeled in light gray are not sampled or characterized as wingless full species.

The text says that the radius vein has 1 5 branches which reach the wing margin but the diagram shows 6 veins doing so. The text says that the media has 1 4 branches which reach the wing margin but the diagram shows 8 doing so. Finally the wing diagram is rotated to make the line segment determining the wing width vertical. The section was made along the line marked with arrows.

Venation of insect wings based on the comstock needham system. In the diagram the width of veins is ignored and each vein is represented by one curve. Für elise by beethoven image credit. The veins are named according to system of comstock and needham modified by wootton.

Adapted from misof et al. It is based on a combination of speculation and fossil data. Redrawn with modifications from chapman fig.

Apart from the vertebrates insects are the only other group of animals to have successfully evolved flight.

Insect wing venation patterns wing contour and shapes of vein bounded domains. In chalcidoidea chalcid wasps for instance only the subcosta and part of the radius are present. Conversely an increase in venation may occur by the branching of existing veins to produce accessory veins or by the development of additional intercalary veins. It shows in exaggerated way corrugation of the wing.

The splines fitted to the wing outline and the venation skeleton comprise the wing diagram. The archedictyon is the name given to a hypothetical scheme of wing venation proposed for the very first winged insect. I am very confused with how to reconcile the diagram of insect wing venation and the written text. The archedictyon is the name given to a hypothetical scheme of wing venation proposed for the very first winged insect.
