- The larval forms usually change in shape during their development and progressive stages are not similar in insects. This change in form is known as metamorphosis. These changes are controlled by a juvenile hormone which is secreted by glands-corpora allata present in the posterior region of insect’s head.

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.

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).

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 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.
Metamorphosis refers to the transformation of a larva to its adult form. This process includes physiological, morphological, biochemical and even behavioural changes 1 . Many animals undergo metamorphosis, like the butterfly.
