What are the four stages of a butterfly s life?

The growth process of a butterfly needs to go through four stages: fertilized egg, larva, pupae and adult, as follows:

1. Fertilized egg.

Different species of butterflies have different egg sizes, and they are usually laid on the foliage of plants.

2. Larvae. After the larvae hatch, they need to eat a lot of food, usually from the leaves of the plant, and go through several peels as they grow.

3. Pupa. After the larvae reach maturity, they use silk to fix themselves and become pupa, which is usually located in a relatively hidden place on the back of the leaves of the plant.

4. Adults. When the pupa matures, the butterfly emerges from the pupae. However, it takes a certain amount of time for the wings to dry and harden, after which they can fly freely.

Distribution:

Butterflies are distributed in all regions of the world, with the most species in the Neotropics, Indo-Australia, and African tropics. Among them, the neotropical region is mainly in the Amazon River basin of South America.

Most concentrated in this area of the rainforest.

The abundant vegetation is home to one-third of the world's butterflies.

Many beautiful and ornamental butterflies are also found in Brazil and Peru in South America.

and other countries. It is followed by the Oriental Zone and the Australian Zone, which are under the influence of the International Union for Conservation of Nature in the world.

Protected species, such as the golden-banded beaked butterfly and the bird-winged butterfly, are found in this area.

There are more than 2,200 species of butterflies in China and more than 2,500 species in India. There are only more than 450 species of butterflies in Australia. Papua New Guinea.

There are more than 1,200 species of butterflies. The third is the African Zone, where the lowland rainforests are home to more than 4,000 species of beautiful butterflies.

The butterfly life cycle is about 14 days.

In general, the lifespan of adult butterflies is about 14 days, two weeks. If the whole life history of butterflies (eggs, larvae, pupae and adults) is counted, the lifespan is about more than a month, but butterflies born in winter live longer.

Most butterflies suck nectar, and in the case of nectar-sucking butterflies, they not only suck nectar, but also love to suck the nectar of certain plants, such as the blue butterfly that sucks the nectar of lily plants; Cabbage butterflies suck the nectar of cruciferous plants; The leopard butterfly, on the other hand, sucks the nectar of plants of the Asteraceae family, etc. There are also some butterflies that feed on the flesh of grapes, and butterflies often suck in grape fields.

The life of a butterfly goes through four stages of development: egg, larva, pupa and adult. The larvae and adults are the only two active periods in its life, and they are completely different and diverse in their living habits. The following describes the habits of butterfly larvae and adults.

1 : The living habits of the larvae.

1 .Feeding.

After butterfly larvae bite through the egg shell and hatch out, some species take a break and directly eat the host plant; Some species (e.g. red-eyed bamboo) feed on egg shells and then plants. There are also some species that need to feed on the old epidermis shed during each molt, such as the butterfly and the butterfly.

The feeding objects of butterfly larvae vary according to the species, and most larvae feed on leaves; Some species, such as pollen butterflies, orange spotted pink butterflies and other food-loving flower buds; There are also some species that eat young pods or young fruits, such as pods gray butterfly eats young pods, and gardenia gray butterfly eats young gardenia fruits. In addition, in the gray butterfly family, there are a few species of larvae that are carnivorous, for example, the scale gray butterfly eats the coffee scale, and the bamboo aphid gray butterfly feeds exclusively on the bamboo aphid, which is carnivorous.

The life of a butterfly will go through four stages: egg, larva, pupa and adult blind worm, and the first three stages are often called juveniles. Butterflies, also known as butterflies, butterflies, floating butterflies, etc., are a general term for a class of insects in the class of insects, veins and lepidoptera, known as "flying flowers", is a very beautiful type of insects.

Butterflies have been recorded in the world nearly 20,000 species, China's butterfly resources are relatively rich, more than 2,000 species have been recorded, most of the butterfly antennae are rod-shaped or hammer-shaped, slender, the bottom is slightly thickened during the day, the two wings are interlocked, and the body is relatively slender.

Most butterflies are medium to large in size, with a wingspan of 15 260 mm, two pairs of membranous wings, and a long cylindrical body, divided into three parts: head, thorax and abdomen, and the body and wing membranes are covered with scales and hairs, forming various color markings.

Adult butterflies use siphon mouthparts to suck nectar, fruit juice, tree sap, sugar or fermented products, and also suck water from streams or mosses, feces of birds and beasts, and body fluids of animal carcasses.
