Describe the external characters of cockroach​

Answer 1

Answer:

Cockroaches are generalized insects, with few special adaptations, and may be among the most primitive living neopteran insects. They have a relatively small head and a broad, flattened body, and most species are reddish-brown to dark brown. They have large compound eyes, two ocelli, and long, flexible antennae.

Answer:

Its body is narrow, elongated, compressed dorsoventrally and bilaterally symmetrical. The adult cockroach measures from 2 to 4 cm in length and about 1 cm in width. The colour is reddish-brown. There are two dark patches surrounded by a light-brown margin in the first thoracic segment.
