Background: Insect metamorphosis proceeds in two modes: hemimetaboly, gradual change along the life cycle; and . The nymphs grow gradually, and the final molt to the adult stage completes the formation of functional wings and genitalia (Belles, 2011).
Background: Insect metamorphosis proceeds in two modes: hemimetaboly, gradual change along the life cycle; and holometaboly, abrupt change from larvae to adult mediated by a pupal stage. Both are regulated by 20-hydroxyecdysone (20E), which promotes molts, and juvenile hormone (JH), which represses adult morphogenesis.
JH + MH larva moults metamorphosis proceeds - JH controls reproductive development - When JH and MH decrease sexual functions initiate - In worker honeybees, JH important in control of age polyethism (schedule of tasks as they age).

Complete metamorphosis refers to change in anatomical and physiological form through a series of life stages. This occurs in the animal world, more specifically the insect world. The majority of holometabolous insects have wings, although there are groups which feature wingless adults. The above image shows the different forms of the ant, from egg to pupal form. It is important to distinguish between the pupal stage and the pupa structure.
Most insects’ life stages move from egg to nymph to pupa to adult, but mayflies .
Most insects’ life stages move from egg to nymph to pupa to adult, but mayflies do not have a pupa stage. Instead, it is the only type of insect to undergo a subimago stage, meaning it’s almost an adult in the sense it grows wing. ut cannot fly long distances and isn’t yet sexually mature. While adult nudibranchs are essentially colorful and ornate blobs of the sea, they don’t start out that way. In fact, after hatching, nudibranch larvae are tiny, plain-looking and have small snail-like shells. The kea is a large, vulnerable species of parrot native to New Zealand, with green and blue feathers on its back and brown and orange feathers on its underside.
