Question

Hind wings of mosquitoes are termed as
A) Coxa
B) Elytra
C) Halteres
D) Tentorium

Answer 1

Hint: There are two pairs of wings in almost all insects. Files have only one set of lift generating wings and one set of halteres. Insects have two pairs of wings, forewings and hindwings; some insects lack hindwings.

Complete answer
Option A) Coxa: Coxa is the first segment of the legs of an insect that is attached to the leg to the thorax. The arthropod leg is a form of appendage that allows the arthropod to walk. The proximal section is the coxa. Hindwings of mosquitoes are not termed as coxa.
Option B) Elytra: The elytra serve first as protective wings. The wings underneath the hind wings, which are used for flying. In some groups, elytra are fused. And render the insect flightless. Hindwings of mosquitoes are not termed as elytra.
Option C) Halteres: Almost all insects have two pairs of wings. Halters can sense even the small deviation in the body position. Halters beat up and down in time with the flapping of the wings along the line pathway. In insects, there are two pairs of wings, forewings and hindwings. Hindwings of mosquitoes are termed halters.
Option D) Tentorium: It is the internal skeleton of the head of insects. The structure of tentorium is an important factor not only for morphology and systematics but also for phylogeny and evolution.

Hence the correct answer is option C.

Note:
Hindwings of mosquitoes are termed halters. Halters help in balancing and improving the flight. There are two pairs of wings in insects’ forewings and hindwings. Some insects have only one pair of wings. Halters provide rapid feedback to muscles to steer the wings and also helps to stabilize the position of the head during the flight.
