Question

In Cockroach, the anterior wings are called
(a) Elytra
(b) Pedipalps
(c) Antenna
(d) Chelicera

Answer 1

They are dark stiff opaque and lathery portions present in the cockroach. They are a modified, hardened forewing of certain insects including cockroaches. They are used for flying.

Complete answer:
The body of the cockroach is enlarged and segmented. They are having a dark brown or reddish-brown color. The body of the cockroach is divided within the head, thorax, and abdomen. The cockroach possesses three pairs of jointed appendages and has two pairs of wings. The fore wings are mesothoracic and are known as tegmina or elytra. Elytra is the pair of wings, which is present in cockroaches. They primarily serve as protective wing-cases as it covers the hindwings, which are used for flying.

Additional information:
Chelicera: A pair of appendages, located in front of the mouth. They present in many arthropods for locomotion and movement.
Antenna: They are present in many insects including cockroaches. The flagellum is the sensory organ present in the antenna which senses the direction and transmits the sound wave. They have many other functions.
Pedipalps: The second pair of appendages are known as pedipalps. We can also see pedipalps in scorpions, spiders, etc. They are not the anterior wings.

So, the correct answer is ‘Elytra’.

Note:
Elytra are also known as wing covers. The exoskeleton is thick and hard and composed of calcareous plates known as sclerites. There are 10 segments present in cockroaches. The segments on the dorsal side (or notum) are called Tergum and on the ventral side is called Sternum. The exoskeleton is covered with wax, which is impermeable to water. They shield the body from the loss of water and give rigidity and a surface for attachment of the body muscles. The adjacent segments are connected through a thin, soft, and flexible arthrodial membrane.
