Zoology - Structural Organisation in Animals Question with Solution | TestHub

Cockroaches show paurometabolous development. This is gradual metamorphosis. In this type the young ones resemble adults and have wings attached to the body. The young forms are known as nymphs. The nymph undergoes 13 times moulting to form adults.  The next to last nymphal stage has wing pads but only adult cockroaches have wings. Thus, the nymph after the last moulting bears both forewings and hind wings.
