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.
Dec 2, 2019 · Many beetle larvae and caterpillars respond by undergoing additional larval molts and becoming giant larvae. By contrast, the same treatments will not cause larvae of Diptera to make an extra larval instar.

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.

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.
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).

Mar 1, 2008 · The larval stage of most holometabolous insects is morphologically and ecologically very different from the adult stage. For example, a majority of butterfly larvae feed on plant tissue, move relatively slowly, and have a limited capacity to disperse to new habitat (Stamp and Casey 1993).
