Tabanid species range from medium-sized to very large, robust insects. Most have a body length between 5 and 25 mm (0.2 and 1.0 in), with the largest having a wingspan of 60 mm (2.4 in). [11] . Deer flies in the genus Chrysops are up to 10 mm (0.4 in) long, have yellow to black bodies and striped abdomens, and membranous wings with dark patches.

Wings are found to be one point discrimination for distinguishing several species of Haematopota, specially colour of veins, pterostigma (ptstg), structure and no. of apical band, no. of rosettes...

Tabanidae is among the most species-rich of all blood-feeding Diptera families. These large flies, 10 to 30 mm in length, impact people and animals via direct effects (nuisance, reduced weight gains in animals) and disease agent transmission.

Generally, the wings of deer flies possess a vertical dark band from the mid-line of the wing down to the margin, while wings of horse flies can be entirely dark, mottled, or completely clear.

Dec 1, 2014 · Most species have clear wings or with a grayish or brownish tinge, however some wings are partially or totally infuscated providing useful features for identification. The wings of Chrysops and Ancala have distinct darkened bands, whereas the wings of Haematopota have patterns of spots or rosettes.

15.2.1 General diagnostic characteristics Theadults ofthefamily Tabanidae arecharacterized bytheir large robust body (6-25 mmlong). Thedeer flies arerelatively slender andusually have patterned wings andmixed bodycolours ofbrown, yellow, orange andblack. A typical coastal deer fly (Chrysops atlanticus Pechuman) ishown i Fig. 15.1. Horse flies (orgreenhead flies) areusually morerobust with ...

Tabanids (Diptera: Tabanidae) are large haematophagous flies that cause both direct (by biting nuisance) and indirect (primarily by mechanical transmission of diseases) damage to host species.

Biting flies of the family Tabanidae are important vectors of human and animal diseases across continents. However, records of Africa tabanids are fragmentary and mostly cursory. To improve identification, documentation and description of Tabanidae ...

the wings are dusty grey and are speckled or mottled (figure 10.1b). The eyes have zig zag bands of iridescent colours, and are widely separated in the females. The antennae are similar to those of Tabanus, but are usually longer and the third segment is straight not curved as in Tabanus and has only three, not four, smal

The tabanids (Tabanidae) are a family of brachycerous diptera insects commonly known as horses that, like the rest of the diptera, only they have two functional wings, the anterior ones.
