Why don't butterflies fly in a straight line?

The abruptly changing trajectory of a butterfly's flight is nothing more than an evolutionary tactic that helps protect them from possible predators.

Why is a butterfly wings

These insects use their wings for several purposes. This is not only a means of flight, but also a kind of warning signs, indicating how poisonous the creature can be. The butterfly is not as adept at flying as other insects, which has evolved to improve its wings for aerodynamics.

However, the line along which these amazing beauties fly is not in vain so chaotic. It is much more difficult for potential predators to pose a specific threat to predict the direction of a butterfly in flight. It can be assumed that the small speed of the moth compensates for some cunning regarding the direction in which it flies.

The flight path of more venomous species is less variable because they have less need for protection.

Research by scientists has shown that butterflies can create additional turbulence when their wings beat. These insects are able to constantly adjust the center of gravity of the body, changing the position of it and the wings.

Some representatives are able to make a sharp 90-degree turn, which, of course, may come as a surprise to potential enemies.

It is known that butterflies cannot fly without pollen, why do dragonflies fly? and got the best answer

Answer from Valera world yao [guru]
The detachment received its name from the scales covering their wings ("pollen") - modified and flattened hairs.
It is not for nothing that butterflies are called Lepidoptera: the upper surfaces of their wings are not smooth, but “shaggy” - covered with hairs and scales. With a sufficiently strong magnification, it is noticeable that each hair that is part of the scale is a microtubule with a number of lateral holes. The conclusion suggests itself that these incredible tweaks in the design are designed to effectively electrify the wings when they rub against the air during the flapping process.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

has two pairs of wings: one pair in an extended position in relation to the other. The wings work asynchronously, that is, while the two front wings are raised, the rear pair of wings is lowered. Two opposite muscle groups move the wings. Muscles are attached to levers within the body. While one muscle group, contracting, pulls up a pair of wings, the other group opens the other pair with a reflex. It is not known exactly, but presumably the pterostigma exists on their wings so that the maneuverability of the wings does not interfere with the main flight.
regulates the flap of the wing and has a mechanical meaning.
The ancestors of modern dragonflies, known from impressions from deposits of the Permian period, also had pterostigma on their wings.

Dragonflies (lat.Odonata) are a group of predatory, well-flying insects. Large, with a movable head, large eyes, short bristle antennae, 4 transparent wings with a dense network of veins and an elongated slender abdomen. The section of entomology devoted to the study of dragonflies is called Odonatology.

I studied the structure of the butterfly's wing.

Butterfly wing structure.

Butterfly wing pattern:
1 - wing root;
2 - leading edge;
3 - rear edge;
4 - top;
5 - near-top area;
6 - back angle;
7 - root area;
8 - middle area;
9 - postdiscal area;
10 - near-marginal area;
11 - edge area.

Slide 10.

Why does a butterfly fly?

Slide 11.

After conducting a survey, I found that most of the children in our class believe that a butterfly cannot fly without pollen on its wings.

Slide 12.

I will definitely tell my classmates about this in the lesson of the surrounding world.

Handling the butterfly can damage the delicate scaly layer that covers the wings. It is enough to harm only a small part of the wing and the whole picture of a picturesque drawing will become far from so beautiful. Moreover, by damaging the outer layer, you can deprive the butterfly of the possibility of normal flight.
.
During the research, I came to the conclusion:
a butterfly cannot fly without pollen on its wings. Erasing too much protective pollen from the wings of butterflies can damage them. If you touch the wing of a butterfly and a moth, dust will remain on your fingers. This "dust" is very fine and consists of small scales, you need to look closely at the wing of the butterfly to see it. These scales help fly, and it is they who are responsible for the color coloration that we see on the wings of butterflies.

No one knows for sure the origin of this word. It is quite possible that it came from the yellow-oily color, most European butterflies call the jaundice butterfly for their greenish-yellow color.
BUTTERFLIES (Lepidoptera) are one of the largest orders of insects with complete transformation, including more than 140 thousand species. The most characteristic feature of the representatives of which is the presence of a dense cover of scales (flattened hairs) on the front and rear wings (while the scales are located both on the veins and on the wing plate between them).
It is divided into more than 100 families. Distributed all over the world, with the exception of areas occupied by glaciers.

Why does a butterfly fly?

Scientists received the answer to this question only when high-speed shooting was applied. It turns out that during flight, the wings of a butterfly first rise upward, closing into a plate, and then swing open to their full width and close under the abdomen. It is interesting that when the wings are raised upward, they are not closed by the entire plane, but, as it were, by a wave moving from the leading edge of the wing to the trailing edge. A channel with a regular oval cross-section is formed between the trailing edge of the wings above the abdomen of the butterfly. It is through this channel that the wings forcefully push the air stream. And just like the exhaust gases ejected from the nozzle of a jet engine lift the butterfly upward.

The meaning of a butterfly in nature.
Butterflies are a miracle of living nature! Butterflies are one of the most beautiful living creatures on Earth!
Most butterflies are pollinators of flowering plants. Species of butterflies, whose caterpillars can produce silk, are primarily useful for humans. Caterpillars of some species of butterflies can be used to combat weeds. And then there are butterflies, the larvae and pupae of which serve to feed the birds.

Butterflies are probably the most beautiful insects. Butterflies have always been a symbol of love, beauty, purity and joy. It is impossible to imagine how these nondescript caterpillars appear lovely creation. Well, let's not get into the lyrics, but just see 15 of the most interesting facts about butterflies.

So, the most interesting facts about butterflies:

• Lepidopterology- a science that studies only butterflies.

• Butterfly eye consists of more than 6,000 parts, therefore it is a very complex organ, despite its diminutiveness.
• Butterflies - very diverse and beautiful insects... Because of this, butterflies have become collectibles. Moreover, butterflies are one of the most popular collectibles. Vladimir Nabokov's collection of butterflies was already 4324 species! Moreover, he discovered 20 of them himself. He later donated this collection to the Zoological Museum of the University of Lausanne.
• Majority butterflies live very shortly- only a few days, but as usual there are exceptions: the lifespan of the Brixton butterfly can be about 10 months.

• There are some types of butterflies that don't eat at all... That is, they do not eat being butterflies. They live only on the food that accumulated in them when they were still caterpillars.
• Different species of butterflies can feed on different types of food... some butterflies like to eat dung or rotten fruit, some like wool, some wax, and some like to eat even the tears of animals.
• There are cases when the caterpillar does not have time to turn into a butterfly in one summer, then it hibernates until the next summer.
• Butterflies do not have ears or other hearing organs, but they can sense everything thanks to vibrations.
• In many Asian countries love to eat butterflies, along with other insects.
• Butterflies have taste buds on their feet. so they stomp on food when they eat.
• In Russia, it was assumed that when a witch or witch dies, then her soul migrates to a butterfly... It was this fact that gave the name to this insect, i.e. from the word "woman".
• The butterflies Calyptra eustrigata do not feed on nectar. They suck the blood of animals gnawing with a sharp proboscis like mosquitoes.

Butterflies are wonderful creatures!

• Despite its short life span, butterflies have time to lay about 1000 eggs.
• Butterflies never sleep.
• The smallest butterfly in the world is the blue dwarf. The wingspan is no more than 1.5 cm. And the largest butterfly in the world is the nocturnal Attacus altas. Its wingspan is as much as 30 cm, so it is often confused with a bird.
