Insect metamorphosis is a fascinating and highly successful biological adaptation, but there is much uncertainty as to how it evolved. Ancestral insect species did not undergo metamorphosis and there are still some existing species that lack metamorphosis or undergo only partial metamorphosis. Based on endocrine studies and morphological comparisons of the development of insect species with and without metamorphosis, a novel hypothesis for the evolution of metamorphosis is proposed. Changes in… Expand
Complete metamorphosis of insects
TLDR
It is proposed that the main adaptive benefit of complete metamorphosis is decoupling between growth and differentiation, which facilitates the exploitation of ephemeral resources and enhances the probability of the metamorphic transition escaping developmental size thresholds. Expand
Puberty & Metamorphosis Related to Reproduction: Metamorphosis, Insects
TLDR
The maturation of the reproductive system in Hemimetabola and Holometabola is discussed, which indicates that the postembryonic development and reproductive physiology of these different subgroups of insects can be divided in 3 major subgroups. Expand
The Evolution of Insect Metamorphosis
  • J. Truman

TLDR
With the evolution of metamorphosis, ecdysteroids acquired a metamorphic function that exploited the repressor capacity of the unliganded EcR, making it a hormone-controlled gateway for the tissue development preceding meetamorphosis. Expand
Endocrine insights into the evolution of metamorphosis in insects.
This review explores the roles of ecdysone and juvenile hormone (JH) in the evolution of complete metamorphosis and how metamorphosis, in turn, has impacted endocrine signaling. JH is a key player inExpand
Imperfect eggs and oviform nymphs: a history of ideas about the origins of insect metamorphosis.

The problem of insect metamorphosis has inspired naturalists for centuries. One question that often arises is why some insects, such as butterflies and bees, undergo a fairly radical metamorphosisExpand
The evolution of insect metamorphosis: a developmental and endocrine view
TLDR
The larva–pupa–adult of the Holometabola to the pronymph–nymph– adult of hemimetabolous insects, a cryptic embryonic stage with unique endocrinology and behavioural modifications that probably served as preadaptations for the larva. Expand
Origin and Evolution of Insect Metamorphosis
TLDR
Holometabolan metamorphosis probably evolved from hemimetabolan ancestors, although the mechanisms underlying such a transition are still obscure. Expand
Transcription factor E93 specifies adult metamorphosis in hemimetabolous and holometabolous insects
TLDR
It is reported that a single factor, E93, controls juvenile-to-adult transition in hemimetabolous and holometabolous insects, thus acting as the universal adult specifier in winged insects. Expand
Metamorphosis and the Impact of Contaminants on Ecological Subsidies
TLDR
This chapter reviews how ecological stressors impact the timing and success of metamorphosis and key ideas include: (1) metamorphotic is a key event in the movement of subsidies from water to land, (2) mortality during meetamorphosis is enhanced in the presence of contaminants, and (3) juvenile responses to contaminants may not predict adult responses, due to death during metamorphoses.

The innovation of the final moult and the origin of insect metamorphosis
  • X. Belles
  • Biology, Medicine
  • Philosophical Transactions of the Royal Society B
  • 2019
TLDR
It is proposed that the final moult, and the consequent hemimetabolan metamorphosis, is a monophyletic innovation and that the role of E93 as a promoter of wing formation and the degeneration of the PG was mechanistically crucial for their emergence. Expand

Metamorphosis : postembryonic reprogramming of gene expression in amphibian and insect cells
TLDR
This book discusses endocrine Cascade in Insect Metamorphosis, Hormone-Induced Changes in Keratin Gene Expression During Amphibian Skin Metamorphoses, and Reprogramming of Genes Expressed in Amphibians Liver During Metamorphotic. Expand
Origin and evolution of insect wings and their relation to metamorphosis, as documented by the fossil record
TLDR
All primitive Paleozoic pterygote nymphs are now known to have had articulated, freely movable wings reinforced by tubular veins, which suggests that the wings of early Pterygota were engaged in flapping movements, and that the immobilized, fixed, veinless wing pads of Recentnymphs have resulted from a later adaptation affecting only juveniles. Expand
Morphogenesis of the wing Anlagen in the mealworm beetle tenebrio molitor during the last larval instar.
TLDR
The wing Anlagen of Tenebrio develop from epidermal cells located on the lateral margins of meso- and metathoraces and show similar development except for cuticular secretion at the end of the instar which is greater on the upper face of the forewings. Expand
Ecdysteroids govern two phases of eye development during metamorphosis of the moth, Manduca sexta.
TLDR
The eye primordium of the moth, Manduca sexta, shows two different developmental responses to ecdysteroids depending on the concentration to which it is exposed, suggesting that ecdySTERoids control development of other tissues in a manner similar to the eye. Expand
The embryonic apolyses of Schistocerca gregaria (Orthoptera)
TLDR
The origin and differentiation of the ecdysial glands and the appearance of the cuticles were studied in embryos of Schistocerca gregaria and in headless embryos explanted in vitro, finding evidence of a cyclic glandular activity in the embryos. Expand
Life History and Habits of Sialis rotunda and S. californica in Western Oregon
TLDR
Comparative ecological studies of Sialis rotunda Banks and S. californica Banks were made in western Oregon from 1966 to 1968 and it was found by rearing individual larvae that there are 10 larval instars, and measurements were recorded of body length and head width of all stadia. Expand
Evolution and Classification of Beetles
TLDR
The beetle ovipositor represents the plesiomorphic form of that found in neuropteroids, so Coleoptera could not be the sister group of any particular neuropteroid order; but Hamilton (48) argued on the basis of wing venation thatColeoptera and Megaloptera are sister groups. Expand
Juvenile hormone titers in the hemolymph during late larval development of the tobacco hornworm, Manduca sexta (L.).
TLDR
The determination of JH titers in heniolymph during the fourth and fifth instars of wild-type Manduca larvae, by means of a sensitive and quantitative JH bioassay utilizing larvae of the black mutant, is described. Expand
Proximo-distal development in the legs of Drosophila.
  • J. Couso, S. Bishop
  • Biology, Medicine
  • The International journal of developmental biology
  • 1998
TLDR
The expression of molecular markers are used to examine how PD development takes place in the legs of the fruit-fly Drosophila melanogaster and suggest a process of regionalization and progressive subdivision of an anlage similar to both insect embryonic segmentation and vertebrate somitogenesis. Expand
GROWTH IN INSECTS
TLDR
The sentiment that insects grow by molting is discussed, which constitutes the Central Dogma of Entomology, which states that an insect does not grow by regular, gradual, and imperceptible degrees like a child, and therefore, growth inside this inexpansible shell cannot be regular and continuous.
