*Holometabolous

Holometabolous; larva emerge from the eggs and do not resemble the adults.  The larva feed, grow and undergoes several ecdyses.  Larvae undergoes a quiescent stage where the outer cuticle hardens to form a pupa, some species have a silken cocoon.  The adult develops inside the pupal case before emerging e.g. Fleas and dipteran flies[[Category:Insecta]]
