About 75% of all insect species go through the four stages of complete metamorphosis - egg, larva, pupa, and adult. The larva is a specialized feeding stage that looks very different from the adult. Fortunately, there are just a few basic larval types and they are relatively easy to recognize.

Protopod larvae – larva have many different forms and often unlike a normal insect form. They hatch from eggs which contain very little yolk. E.g. first instar larvae of parasitic hymenoptera. Polypod larvae – also known as eruciform larvae, these larvae have abdominal prolegs, in addition to usual thoracic legs.

TYPES OF LARVAE AND PUPAE EGGS The first stage of dev. lopment in all insects is egg. Maj. rity of insects are oviparous. Egg stage is inconspic. ous, inexpensive and inactive. Yolk co. tained in the egg supp. rts the embryonic development. Eggs are …

2019年12月12日 · Some insects go through gradual metamorphosis in three stages from egg to nymph to adult. In their nymph stage they look essentially the same as in their adult stage …

After fertilisation, the eggs develop into tiny larvae. The larvae develop and grow for some time before metamorphosing into adults. Most marine invertebrates and many fish have a pelagic larval stage or pelagic eggs. These live in the plankton, and may be transported long distances.

2025年3月20日 · During the larval stage, insects grow by molting, shedding their exoskeleton as they get larger. Each period between molts is called an instar. Thus, a first-instar larva is the stage directly after hatching, while a second-instar larva comes after the first molt, and so on.

2011年4月29日 · Complete metamorphosis begins with the insect hatching from an egg into a soft worm-like shape called a larva. Larvae have a very big appetite and can eat several times their own body weight every day.

2021年11月15日 · A large number of insects undergo complete metamorphosis, which comprises four distinct developmental stages called: egg, larva, pupa, and adult. Based on the species, the egg hatches into something like a worm, it is the larva that then molts multiple times.

2024年4月16日 · Adult female Aedes mosquitoes lay eggs on the inner walls of containers that hold water. Larvae hatch from mosquito eggs and live in water. Larvae develop into pupae. Pupae develop into adult, flying mosquitoes. Adult female mosquitoes bite people and animals. Mosquitoes need blood to produce eggs.

Holometaboly has four life stages: egg, larva, pupa, and adult (or imago). Holometabolous insects have a life cycle where the egg hatches into a larva, then develops into an inactive pupa stage and after that develops into a complete adult.
