Dec 2, 2019 · The larval form, then, arises from the arrest of ancestral patterns of tissue growth and patterning. The structures that are organized prior to the arrest are adapted to the larval form, while the remainder of the primordium is carried forward to contribute to the adult system (Figure 2 A).

The caterpillar larvae of butterflies and moths are specialized for feeding, whereas their adult forms are specialized for flight and reproduction, often lacking the mouthparts necessary for eating. The division of functions between larva and adult is often remarkably distinct (Wald 1981).

Jul 26, 2019 · Larvae grow and molt, usually multiple times. Some insect orders have unique names for their larval forms: butterfly and moth larvae are caterpillars; fly larvae are maggots, and beetle larvae are grubs. When the larva molts for the final time, it transforms into a pupa.
Aug 26, 2019 · Key transcription factors are associated with the holometabolous life stages: Krüppel-homolog 1 (Kr-h1) in the larva, broad in the pupa and E93 in the adult. Kr-h1 mediates JH action and is found whenever JH acts, while the other two genes direct the formation of their corresponding stages.

What is a larval stage?
Like a chicken egg, a butterfly egg has a shell to protect it and a yolk to provide food as the embryo develops. Some butterflies lay only a single egg at a time, while others can lay 100 at once. Larva. Insects begin their life as a worm-like larva. Butterflies and moths are no different–we just call them "caterpillars" instead.
