Q

wings and legs free from body and can be seen externally
e.g BEETLES

A

Exarate

17
Q

wings and legs bound to body by moulting fluid but still visible externally
e.g MOSQUITO

A

obtectate

18
Q

last larval skin retained; hardened skin (puparium) encloses pupa hence it can not be seen externally
e.g Musca, Oestrus

A

Coarctate
