External images For terms, see: Morphology of Diptera. Wing length: 6.5–8.75 mm (0.256–0.344 in). This species closely resembles Melangyna ericarum, but the thorax has pale hairs on the disc (many black hairs in M. ericarum). The jowls have only pale hairs below the eyes, whereas M. ericarum has some black hairs.
External images For terms see Morphology of Diptera. Wing length 6-7·25 mm. Antennae reddish. In front view the distance between the eyes at most equal to the width of an eye. Wings blackish-tinged. Female thorax with purplish reflections. The male genitalia are figured by Maibach, A. & Goeldlin de Tiefenau (1994).
External images For terms see Morphology of Diptera Wing length 7·25–9 mm. Males only four spots on the abdomen. Female tergites black, pale abdominal markings absent. Eyes with short hairs. The male terminalia are figured by Hippa (1968) ). [3] Larva described and figured by Rotheray (1994). [4] See references for determination. [5] [6] [7] [8]
In the flexed wing, the outer squama of the alula is turned upside down above the inner squama, the latter not being affected by the movement of the wing. In many Diptera, a deep incision of the anal area of the wing membrane behind the single vannal vein sets off a proximal alar lobe distal to the outer squama of the alula. [38]
Diptera is an order of winged insects commonly known as flies. Diptera, which are one of the most successful groups of organisms on Earth, are very diverse biologically. None are truly marine but they occupy virtually every terrestrial niche. Many have co-evolved in association with plants and animals.
For terms see Morphology of Diptera. Wing venation. Dixidae are small (body length not more than 5.0 mm) slender gnats with thin legs. Adults are black to yellowish-brown. [4] The head is relatively broad. The antennae are thin and the flagellum has 14 segments. The proboscis is short and thick and the palpi are five-segmented.
For terms see Morphology of Diptera.. Wing length 6.5-8.5 mm. Sternite 2 yellow with blackish crossband. Female frons with large patches of dust. Tergites 3 and 4 with equally-sized yellow patterns Tergite 2: pale pattern always present, as broad as or broader than pattern on tergites 3 and 4.
