Why don't butterflies fly in a straight line? Butterflies and the most interesting facts about them So, the most interesting facts about butterflies
One of the most vivid childhood memories for me was visiting the Ipatiev Monastery (Kostroma region). But it is unlikely that a six-year-old child can understand the historical and cultural significance of this ancient spiritual monastery, or be imbued with the grandeur and splendor of this architectural monument. An indelible impression that remained in my memory for the rest of my life was made by.... insect exhibit housed there!
After the modest colors of Siberia, it was amazing - powerful beetles with huge antennae, spiders, the mere sight of which made you want to take your mother’s hand tightly, and, of course, butterflies! So colorful, colorful, small and the size of a plate! Many years have passed since then, but I still remember well that feeling of delight... Oh, if only they had given me a book then Diana Aston and Sylvia Long's "The Butterfly Takes Time"...
The first spread of the book tells us how the life of a butterfly begins.
On the next page, the caterpillar has already turned into a pupa, and here it is shown what amazing metamorphoses happen to it over the course of 45 days. It turns out that an insect can increase in size by 30 thousand times! How hard it is to believe!
Butterflies are so fragile and defenseless, they face many different dangers, how can they protect themselves from enemies? How intelligently and harmoniously everything was created by nature! For example, a butterfly called callima looks like a withered autumn leaf, and this camouflage allows it to blend into the landscape. Or another insect - the peacock's eye - in case of danger, begins to rub its wings against each other, and an unpleasant sound is heard, reminiscent of a hissing...
This amazingly colorful book allows you to learn a lot of interesting facts about butterflies:
- The fact that some insects, which are very bright and beautiful in appearance, can be poisonous (again, this is a kind of signal warning of danger)!
- About the fact that not all butterflies have the same menu, there are also visitors to the “mud club” among them. What kind of club is this? You can learn about this by studying the book...
- About the giants and midgets of the butterfly world. The world's largest butterfly lives in New Guinea, and has a majestic name - Queen Alexandra's birdwing (its wingspan reaches 30 centimeters), but the "baby" - the dwarf blueberry, found in Europe and Asia, may not be noticed (this insect less than one centimeter).
- About the difference between night and day butterflies. Interesting figures: the first appeared on Earth 190 million years ago, and the second are very “young”, only some 40 million years ago...
I think that young entomologists who thoroughly understand the life of insects will choose another book that claims to have encyclopedic scope and scientific depth. But this particular publication can become the starting point for a child to develop such a hobby.
And even if this does not happen, then getting acquainted with the book is a great opportunity to expand your horizons (this applies not only to children, but also to adults) and get great pleasure from looking at the beautiful illustrations.
And, of course, get an answer to the main question, why is the butterfly in no hurry?
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 order received its name from the scales (“pollen”) covering their wings - modified and flattened hairs.
It’s 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 included in the scale is a microtubule with a number of side holes. The conclusion suggests itself that these incredible design tricks are designed to effectively electrify the wings when they rub against the air during flapping.

has two pairs of wings: one pair in an extended position relative to the other. The wings work asynchronously, that is, while the two front wings are rising, the rear pair of wings is lowering. Two opposing muscle groups move the wings. Muscles are attached to levers inside the body. While one group of muscles, contracting, pulls up a pair of wings, another group opens the other pair with a reflex. It is not known for sure, but presumably the pterostigma exists on their wings so that the maneuverability of the wings does not interfere with the main flight.
regulates wing flapping and has mechanical significance. 
The ancestors of modern dragonflies, known from imprints from sediments of the Permian period, also had pterostigmas on their wings.

Dragonflies (lat. Odonata) are a detachment of predatory, well-flying insects. Large, with a movable head, large eyes, short bristle-like antennae, 4 transparent wings with a dense network of veins and an elongated slender abdomen. The branch of entomology devoted to the study of dragonflies is called Odonatology.
The sharply changing flight path of a butterfly is nothing more than an evolutionary tactic that helps protect them from possible predators.
Why does a butterfly need wings?
These insects use their wings for several purposes. These are not only means of flight, but also a kind of warning signs indicating how poisonous the creature can be. The butterfly is not as skilled in flight as other insects, which were able to evolve wings for aerodynamics.
However, the line along which these amazing beauties fly is not for nothing so chaotic. It is much more difficult for possible predators that pose a certain threat to predict the direction of the butterfly in flight. It can be assumed that the moth compensates for its low speed with some cunning regarding the direction in which it flies.
Flight path more poisonous species less fickle because they have less need for protection.
Research by scientists has shown that butterflies can create additional turbulence while beating their wings. 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 capable of making a sharp 90-degree turn, which, of course, may come as a surprise to potential enemies.
