The three stages of the ancestral insect species - pronymph, nymph and adult - are proposed to be equivalent to the larva, pupa and adult stages of insects with complete metamorphosis.
All flies pass through four life stages: egg, larva, pupa and adult.
When a male molts from a larva to a pupa , the horns evert, unfold, and stretch out to their full shape and length - not unlike extending a collapsed telescope.
The adult flea is an excellent jumper passing through a complete life cycle consisting of egg, larva, pupa and adult.
The type of pupation site selected by larvae also affects pupal survival of D. melanogaster.
Red stripe appears as a diffuse stripe of pigment on the dorsum of larvae and pupae and is variable in expressivity and penetrance.
All of these results show that the pupal male was almost always killed by the already eclosed male immediately after, or even before, eclosion.
Emerged adult Axarus and shed pupal exuviae were removed from the trap daily.
Around her were tiny, silver eggs, chubby larvae, and pupae folded like mummies inside translucent cases.
The house fly has complete metamorphosis: egg, larvae, pupae and adult.
