What do insects eat? What food do insects eat

Insect. Depending on the type, the way of eating and the type of food are also different. Their food is diverse, whether it is animals, plants, wood, spoilage, etc., it can become food.

Generally speaking, depending on the nature of food, it can be mainly divided into several categories, such as herbivorous, carnivorous, carrivorous and blood-sucking. Herbivorous insects are the most numerous, accounting for about 48% of the total number of insects. But the parts where they feed are different.

Soil insects such as beetles, needleworms, mole crickets, etc., feed mainly on the roots or seedlings of crops. The adults of goldenrod insects, the larvae of armyworms, and the larvae of cabbage butterflies all feed on the leaves of plants. The locusts not only eat the leaves, but also bite off the entire stem.

The larvae of the beetle popping worm eat away at the cambium layer of the tree, thus killing the entire plant. The larvae of the longhorn beetle feed on the wood department. Some insects do not feed on roots, stems and leaves obviously, but they inhabit various parts of the plant and suck the sap, causing the plant to wither and die.

There are different types of insects and different things they like to eat. Insects are herbivorous and eat plant roots, seedlings, fruits, flowers, etc.; Carnivorous, eating other small insects and molluscs; Rotten, eating carcasses, carrion, feces, etc.; omnivorous, with a wide range of foods; It is blood-sucking and feeds mainly on the blood of higher animals.

Insects drink dew, and some insects eat the leaves of plants.

Food plays a decisive role in the life and distribution of insects, and different species of insects have obvious selectivity and adaptability to their own food.

For example, cabbage worms, which harm cabbage, do not eat corn.

There is also a close relationship between the size, amount and color of the insect body between food, for example, the rice elephant and the bean elephant that steal the grain, the whole body has to burrow into the grain grain, and their body will never exceed the size of the grain grain;

The juvenile stage of corn borer is to eat and live in plant stalks and does not come into contact with light, so the color of its body is mostly white or grayish-white.

The feeding habits of insects vary depending on the species, such as:

1.Herbivorous: This type of insect feeds on the roots, stems, leaves, flowers, and fruits of plants, such as aphids, bees, etc.

2.Carnivorous: This type of insect feeds on other insects, animal carcasses, carrion, etc., such as flies, mosquitoes, cockroaches, etc.

3.Satrivorous: This type of insect feeds on animal carcasses, carrion, etc., such as feces shells, earthworms, etc.

4.Omnivorous: This type of insect eats a wide range of foods, including plants, animals, spoilage, etc., such as butterflies, ants, etc.

5.Blood-sucking: This type of insect mainly feeds on the blood of higher animals, such as mosquitoes, flies, etc.

The above are some of the eating habits of insects, I hope it will help you.

There are two types of insect eyes, one is called compound eye and the other is called single eye. The head of an insect generally has a pair of compound eyes, which are composed of many small eyes, each of which is hexagonal, but this does not mean that there are as many small eyes as there are to see how many flowers, but each small eye can only see a part of the object, and the whole eye sees the object like a patchwork.

Insects have a very wide field of vision, they are not like our eyes, they can only see objects in front of them. Lo and behold, the compound eyes of the protruding eye fly are born on the stalk-like protrusions on both sides of the head, and it can see objects in all directions, and it is not easy to approach it. In addition to the two main compound eyes, many insects also have several small eyes, known as monoculars, each of which consists of only one small eye, and the function of the monocular may only be to distinguish the brightness and darkness of light.

There are so many types of insects that they eat a variety of different plants and even meat insects.

1. There are many kinds of insects, different forms, belonging to the arthropods in the invertebrates, and they are the most numerous animal groups on the earth, accounting for more than 50% of all biological species (including bacteria, fungi and viruses), and their traces are almost everywhere in the world.

2. Insects have a wide range of eating habits: they are divided into herbivorous - various leaf beetles and flower beetles; Carnivorous - step armor, tiger armor; Decaying - Yan Jia; Necmodal - burial armor; Fecal-feeding - dung beetle.

3. The lifestyles and living places are bound to be diverse, and the lifestyles and life instincts of some insects are of great research value. It can be said that from the end of the earth to the cape, from the mountains to the abyss, from the equator to the poles, from the ocean, rivers to the desert, from the grassland to the forest, from the field to the indoors, from the sky to the soil, insects are everywhere.

4. The larvae of insects will gradually become larger during the growth process, and the exoskeleton and ** on their surface will be swelled by the gradually larger body. Slowly, larvae"Coats"It begins to fall off, creating a new layer of larger, harder epidermis. The larvae undergo multiple metamorphoses before they grow into adults.

What do insects not eat? ！Since insects are the most diverse life forms on Earth, almost all organic matter on Earth (in the chemical definition of the word, like carbon-based) can be consumed by certain insect species at some stage of their lives.

First of all, almost all plants and plant parts are edible. Roots, stems, leaves, flowers, sap, bark, wood, thorns, pollen, nectar seeds, fruits, spores, etc. Different species can specialize in certain parts:

For example, there are xylem specialists and phloem specialists (these two types of plant sap). It's safe to say that for every part of every plant on Earth, there is an insect that can eat it. Some insects even make their own food:

Bees make honey from nectar and ferment the pollen into "bee bread".

What about seaweed? It refers to the fact that the sap is not a plant, but an algae ......But certain insects eat it too! Aquatic insects are mainly found in rivers, but there are very few marine species that live near the coast.

Similarly, there are insects that eat fungi: mushrooms, molds, and yeasts. Some tiny insects (and other hexapods that aren't technically insects, like springtails) will even eat bacteria!

As for animals, insects also eat them. Insects, of course, eat other insects. Every life stage of almost every insect – eggs, larvae, nymphs, pupae and adults – can be eaten or parasitized by another insect.

The latter refers to parasitic wasps, which lay eggs on other insects or animals, and the developing larvae eat their hosts from the inside out. In addition to this, there are insects that hunt and kill other animals, usually anything smaller than them: worms, fish, birds, tadpoles, anything.

Minorities, such as ants, can work together to kill larger beasts. The others are parasites (not to be confused with parasites) that will eat part of a large animal without killing it. Vampire insects are a good example of materialism, but a few insects can infect living tissues in rare cases.

That's living tissue: insects also eat the dead. They can eat decaying plant parts, such as fallen trees or decaying juice.

Others eat rotting animal parts. Different species of insects (mainly flies) eat freshly dead, decomposing corpses and dried mummies. Some insects eat hair, feathers, or fur.

Some people eat the dried shells of other insects or remove dead insects from frozen, dried, poisonous, or greasy wasteland. Some eat feces. If insects don't eat all these nasty things, the world will fall into the abyss of death, feces, and disease.

Many man-made items are ...... made from organic matterThese are also edible! Insects can eat plant products, from cereals to flour to bread and baked goods. They can eat paper ("bookworms" are actually insects) and wooden furniture and houses.

They can eat leather, glue, wool, cotton, herbs, spices, and even certain medicines and medicines. Essentially, if it's not made of minerals, metals, or petroleum (with some exceptions), then insects can eat it.

1. Silkworm pupae, containing 28% 30% fat, 56% 63% protein, calcium, phosphorus, iron and other minerals, rich vitamins and hormones and other components. The protein contained in it is easy to be hydrolyzed, and is similar to human protein, and the human absorption rate is about 90%.

2. Grasshopper, also known as Zhi, its cicada molt and male cicada can be used in medicine. The newly unearthed old larvae are rich in nutrition, with a protein content of 58-58% and a fat content of 10-32%. The cicada body is rich in nutrients, with a dry protein content of more than 70%, a fat of about 7%, vitamins and various beneficial trace elements are higher than that of general meat foods, and it can be called the king of protein in today's food.

3. Bamboo insects, larvae long barrel-shaped, milky white, rich in protein, amino acids, fatty acids, which good mineral elements, vitamins and other nutrients, protein content up to 30% 40%, Li Cheng lead amino acid content, crude fat content is.

4. Bean worm, bean worm is a high-quality protein resource, bean worm protein is more suitable for human needs than meat, fish, and plant protein, and the composition is more reasonable. Rich in nutritional value and with high development value, the composition of bean worms is mostly protein in addition to water, accounting for dry weight.

5. Bee pupa, bee pupae contain protein, fat, carbohydrates, trace elements, and water. The nutritional value of bee pupae is not lower than pollen, especially the content of vitamin A is much higher than beef, and the protein is second only to dried fish oil.
