richest countries in terms of the variety of butterflies can be called Brazil, Peru, Indonesia, China, and in general all the tropical regions of the planet.It lives most of the more than 150 thousand currently known species of butterflies which are often hit by its size and color.

one of the poorest countries is Greenland - lives there only five species of butterflies, and in some small oceanic islands and in Antarctica are none at all.Generally, one of the famous people said that butterflies like no transfer image of the country.South of the country - bright, colorful, cheerful, they are and butterflies.In the Nordic countries butterfly dim, blurry pastel colors.

Why such a beautiful butterfly?

It only seems to us that they are a manifestation of "extravagance" of nature.In fact, the butterfly is mainly colored by very prosaic reasons.One of them - a disguise, that is, the butterfly thus "hiding" in his natural environment.For example, living in the highlands o
f the European Group of butterflies - Parnassians.This is a big family, which has about a hundred species, refers to him, in particular, is almost legendary in our Apollo.It - translucent butterflies that seem to transmit crystal transparency of the air, paint glaciers, clear sky.They seem to blend in with the landscape in which they live.Another group - black cumin.They are brown or black, with ocher - it is also an attribute of high mountains, cliffs, where the dark color makes it easier to accumulate solar heat in cold climates.Another purpose inks - knocking down a wing.It is known that birds are very good vision to the same color.Here they see an insect fly and have to eat it, all of a sudden a butterfly spreading its wings, and there, for example, there are large eyes.The bird is frightened for a moment, and in the meantime the butterfly escapes.

In fact, the wings of butterflies are covered with thousands of tiny scales that give it a bright color.These scales have a variety of textures and, as a rule, different colored dyes - pigment, which depends on the image on the wings and their color.Sometimes scales are colorless, but due to the shape of the prism, they refract light in such a way as to create whimsical play of all colors.Hence the variety and play of colors on the wings of butterflies.

Who is prettier - male or female?

male.Females are usually larger, but the males - beautiful.This is due to reproduction.The fact that the butterfly reproduce only once.And while the female egg is not postponed, it must be as inconspicuous as possible, not to get someone "to the tooth".A beautiful males, however, to reproduce it has a fairly low value.The male finds the female by smell, that is important pheromones, not painting.This is a very delicate mechanism: there are species that are female for a few kilometers.But when the female is already fertilized, the smell changes, and it no longer attracts the males.

Does global warming to replace the population of butterflies?



Global fauna changes caused by warming, yet, but certain trends can be traced.For example, you can often find hawk convolvulaceae: a tropical look, which, however, migrates to the polar circle.These butterflies fly from the Mediterranean in the spring, lay eggs, laying a new generation that is growing.Autumn leaves of a different butterflies - local generation, which in September can often be seen in the gardens among the flowers.But that local generation is not fruitful, here it dies.There is a simple reason: in the last few thousand years in Europe several times a changing climate.Glacial periods alternated warming.These butterflies are genetically incorporated, they must fly north - apparently before there were such conditions that they have evolved and migrated smoothly.Who I am here for them too cold.But let us imagine that the temperature will rise a few degrees, the butterflies will inhabit the territory far to the north, and in our territory will be new thermophilic species.
