V
vector
In medical entomology, a vector is an arthropod which carries disease producing organisms (bacteria, virus, filarial worms) to a vertebrate host. For example, several species of Culicidae are vectors for malaria.

venter
The side of the fly that we would indicate as 'the belly' in human terms. On practice this means the side where the mouth is positioned an where the legs are placed.
Adjective: ventral.
Opposite: dorsum.
ventral
1. Located on the venter. For legs this means that these are considered as if they were in the position as given in the illustration. So, even if a leg is pointing upwards in a specimen, one should image that the leg was positioned in a horizontal plane, perpendicular to the body axis.

2. Located in a more position towards the venter. For example, a seta can be located ventral to another seta.

Opposite: dorsal.
ventrite
The ventral surface of one of the body segments. An old term
and now considered synonym of sternite.
vertex
Quote from the Manual of Nearctic Diptera:
The median portion of the upper extremity of the head, bounded by the eyes latterally, the occiput posteriorly and the frons anteriorly, ...

Thus it becomes a rather roughly defined area you could call the posterodorsal margin of the head, in the middle of which you will find the (posterior part of) the ocellar triangle.
vitta
Plural: vittae.
A broad stripe, most often used while describing longitudinal bands on the thorax but can be used for the abdomen and head, when it mostly will be used to describe a cross-band.
E.g.: "Presutural area of scutum with irregular dark brown vittae on lateral margin -Oestrophasia (Cenosoma) sabroskyi."
