There are a few further conditions that may vary development. Define the following, and give an insect example.
1. Diapause
2. Hypermetabola
3. Sub-imago
The more recently derived (evolved) insect orders are the holometabolous orders while ametabola, then hemi- and paurometabola are considered more primitive conditions. With the energetic expenditure of metamorphosis and the extended time spent in a vulnerable pupal stage, why do you supposed was favored as a life history strategy and preserved evolutionarily? What are the benefits or reasons for metamorphosis? Defend your answer.
