To date, all of the Lower Cretaceous tabanids share the typical tabanid characteristic in wing venation: R4+5 furcated near to wing apex, and forming a large, wide Y shape just across the wing apex. The wing venation is characteristic, especially the branching of the fourth longitudinal vein. Undescribed Tabanidae have been noted from the Eocene Wing hyaline, stigma brown. Two competing males may vibrate their wings, then lunge at each other and butt heads like tiny rams. They prefer to fly in sunlight, avoiding dark and shady areas, and are inactive at night.

Source. The venation of the wing-blade is characteristic [rendering craneflies directly as such recognizable] also by the shift towards the distal end of the wing of cross-veins and of the forks of the majority of longitudinal veins, determining the special nature of the venation as a whole and of the aerodynamics of the wing. The wing venation is consistent within the Tabanidae; a key feature is the widely divergent R4 and R5 veins, which fork and enclose the apex of the wing. 7B). National Museum of Natural History. Drawings by Division of Plant Industry. Second posterior cell closed and petiolate before the hind margin of the wing; fork of third longitudinal vein with appendix.

Emphasis is placed on diagnostic characters that distinguish the various groups and species. This case was discussed by the same author in a study published in 1965, when it was hypothesized that the alterations were due to atavism, as they would be similar to the intercalating wing veins normally Abdomen subshining black.

Portal to information on the insect order Diptera (flies and midges) and a forum for researchers on the insect group. Palpus long and slender subequal to antenna length. To identify less common species, you will need to use reference books such as CSIRO's "Insects of Australia" (call #QL487.15). The wing-venation [that is the venation of the wing-proper, the wing-blade] remaining rich, essentially not being reduced, turns out to be a very useful supporting skeletal element of a large wing.

Wing venation of Philopotinae, in turn, can be either complete or extremely reduced.
