throughout the body
veins are present throughout the body as tubes that carry blood back to the heart. veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, and large vs. small. 









































bullet::::- superficial veins are those closer to the surface of the body, and have no corresponding arteries.









































bullet::::- deep veins are deeper in the body and have corresponding arteries.









































bullet::::- perforator veins drain from the superficial to the deep veins. these are usually referred to in the lower limbs and feet.









































bullet::::- communicating veins are veins that directly connect superficial veins to deep veins.

the thorax is broad and moderately convex, with long bristles (macrotrichae). the legs are long and slender, with femora and tibiae bearing bristles; the tibiae are without apical spurs and the tarsi are provided with empodia or without the median pretarsal. the wings are well developed, hyaline or opaque, often with pigmentation of the veins located at the termination of the transverse and longitudinal veins.









































the abdomen is tapered and elongated, typically 3 to 4 times as long as its broadest width when not extended for activities such as oviposition. eight abdominal segments (uriti) are externally visible.
