Tegmen

Tegmina ( singular tegmen or the tegmentum, lat ceiling, dome of tegere cover ) are wholly or partially thickened ( chitinisierten ), enhanced ( sclerotized ) and pigmented top wings of insects always still show a distinct venation. These veins is derived from the tracheae and gives the wings in addition stability.

Tegmina are key components in stick insects ( Phasmatodea ), cockroaches ( Blattodea ), Short ( caelifera ) and long horned crickets ( Ensifera ) to find.

To be distinguished, they are can be found from the more sclerotized and always loose vein elytra, elytra a type of any of these beetles ( Coleoptera).

For function, shape, size and location in the flight deck see wings.
