Question

Development of cockroach is:

• A. Holometabolous
• B. Ametabolism
• C. Paurometabolous
• D. None of the above

Answer 1

The correct option is C

Paurometabolous

Complete metamorphosis is one of two types of metamorphosis exhibited by insects. In complete metamorphosis an insect goes through four distinct stages: Egg. Larva. Pupa.
The development of P. americana(cockroach) is paurometabolous, meaning there is development through nymphal stage. The nymphs look very much like adults.
Holometabolism, also called complete metamorphism, is a form of insect development which includes four life stages – as an embryo or egg, a larva, a pupa and an imago or adult.
Ametabolism is a type of growth or life cycle in insects in which there is slight or no metamorphosis, only a gradual increase in size. It is present only in primitive wingless insects, e.g. order: Thysanura (Silverfish).
