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. Wing membranes are clear in some species and variously darkened in others, providing useful taxonomic characters, particularly for Chrysops spp. Waray hini subspecies nga nakalista. The wing venation was studied by Shannon & Bromley (1924). Emphasis is placed on diagnostic characters that distinguish the various groups and species. Various wing movements (flicking, waving, extending, and fanning) are used for mate attraction and to ward off rivals. Secondary reduction is more extreme in the wing of a pteromalid wasp (Hymenoptera: Pteromalidae), which may be Head length 0.5 mm, thorax length 1.0 mm, abdomen length 1.3 mm; wing length 2.7 mm, width 1.2 mm. Aquatic Hymenoptera (Parasitic Wasps) of Michigan - Identification [under construction] A number of parasitic wasps have come adapted for aquatic existence by attacking various life stages (principally eggs, larvae and/or pupae) of aquatic insect groups, especially those of Heteroptera and holometabolous orders (e.g., Lepidoptera, Coleoptera, etc. Xylocopa generally resemble bumble bees in size and somewhat in color, being black, metallic bluish or greenish black, or purplish blue. Scudder (1895) recorded a possible new genus and species of tabanid from the Miocene Oeningen deposits of Switzerland. These long proboscides are used to probe for nectar in deep-throated flowers. distinguished by the wing-venation. Contributed by Cotinis on 7 July, 2012 - 10:06pm.

Tabanus (Neotabanus) enanus n. sp (Pl. 1, fig. 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. Legs slender. 7. Second posterior cell closed and petiolate before the hind margin of the wing; fork of third longitudinal vein with appendix. Addthis Share Tools. CREDITS & ACKNOWLEDGMENTS: Illustrations include drawings and photographs of living and preserved collection specimens. A cross-sectional study was carried out from March to May 2014 to determine an apparent density of the tsetse and other biting flies in selected peasant associations (PAs) of Gimbi district. Source. Horse-flies (for other names, see common names) are true flies in the family Tabanidae in the insect order Diptera.They are often large and agile in flight, and the females bite animals, including humans, to obtain blood. Some males have yellowish areas on the face. 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. It is known from the eastern and southern United States and the Gulf coast of Mexico. In the first group the third segment of the an- tenna is clearly ringed, showing that it is made up of several segments grown together.

Long-tongued horse flies (Diptera : Tabanidae : Pangoniinae) have proboscis lengths at least as long as their heads, the longest belonging to the Old World genus Philoliche (Wiedemann, 1820).
