Question

Explain the features of the body of cockroach which enables it to move and fly

Answer 1

Periplaneta americana or cockroaches are cursorial insects, that is they can run very fast in order to escape their predators. They fly very rarely as they are not very good fliers.
If attributing to the movement of cockroach and the ability to fly, they have thoracic appendages for that, which connect and bear three pairs of legs and two pairs of wings.
Each thoracic leg bear walking legs which help them to move along the ground and are divided into three parts which all assist in the movement in ground for cockroaches.
The wings are two in pair of a cockroach. The movement of the wings are controlled by a special set of muscles. There are even two types of wings, Mesothoracic or forewings and Metathoracic or hindwings.
Forewings are thick, leathery, opaque and dark coloured structures, which are surrounded by somewhat narrow at the distal end. They are not used for flight, but cover and protect their Metathoracic wings. They are also called as wing-covers or tegmina or elytra.
The Hindwings or Metathoracic wings are delicate, thin, transparent and membranous structures with a broad terminal end. They are definitely used for flight, but in a resting state or position, lie folded below the tegmina. They are attached with the antero-lateral margin of the Metathoracic tergum.
In all the wings are used for flight but only Metathoracic and also in a short flight.

The body and legs of cockroaches have hard coverings forming an outer skeleton. The muscles of the breast connected with three pairs of legs and two pairs of wings help the cockroach to walk and fly.
