Patterns of Metamorphosis
The pattern of metamorphosis is not the same in all insects and so metamorphosis can be broadly classified into 3 types:
(1) Complete metamorphosis as observed in Endopterygota-Holometabolous development.
(2) Incomplete metamorphosis as observed in Exopterygota -Hemimetabolous development.
(3) Slight or no metamorphosis as observed in Apterygota-ametabolous or direct development.
