Oct 19, 2023 · The idea that a small organism can have a large effect on a physical system is often referred to as the butterfly effect. If Katija’s theory is confirmed, it could change our understanding of ocean circulation and influence future global climate models.
He noted the difference between insects that show a gradual transformation as they moult and grow, such as grasshoppers, and those such as flies and butterflies that have a larval and then a pupal stage before emerging as an adult.
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 · The altricial strategy in insects, though, while involving the suppression of embryonic programmes, does not result in a partially developed, helpless nymph. Rather, the result is a specialized larval form that can live independently from the very moment of hatching.

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).

Oct 4, 2017 · A butterfly larva first emerges from its egg as a caterpillar, chewing its way out of its protective shell. It keeps munching large quantities of leaves, growing and shedding its skin as it outgrows it.

How does a moth differ from a larva?
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).
