Butterflies are so wonderfull

Butterflies probably in the Cretaceous, if the climate were different continents, with the difference that today. That is, if the major broadcast Angiosperms took place. Evidence forfeit of paleontology, where some 50 butterfly fossils have been identified, the morphology and the study of homologies, molecular genetics and biochemistry of Comparative Ethology comparison, and the current geographical distribution and the 'ecology. The researchers are in favour of chalk, originally developed for the butterflies generally positive vicariant zoogeographic hypothesis on how the broad outlines of butterflies distributed, came into the world, while those that promote a greater age dispersalist on assumptions. Some species in the eyes moths use of ferns that the larvae of the plant guests, and it is possible that the butterflies, before Angiosperms their current crop guests. The study modern butterfly classification began with Ehrlich phenetic use of hundreds of hitherto neglected morphological characteristics in the form of tables, families and large corporations. Scoble (1995) and continue the search for new characters, but with its implementation in cladism. Lavral characters are now often integrated into the world of adult butterflies. The addition of molecular data, the researchers were able to solve in many cladistic lignages.
Currently, the butterflies in three superfamilies, Hedyloidea, consisting of the "American butterflies butterfly," Hesperioidea, consisting of the "boss" and Papilionoidea or "butterflies applicable". The latter two are likely superfamilies sister taxa, so that the butterflies are common thoughts, a group of natural or clade.
The range depends on the name butterfly, the extent to which the concept expanded. Currently, most experts conclude superfamilies Hedyloidea (the Americans butterfly butterflies the night), Hesperioidea (Skipper) and Papilionoidea (the so-called "real" butterflies). This concept of butterflies, including the Hedyloidea was recently expanded, but it makes the group a natural Clade, Rhopalocera.

Butterfly eggs from a CD-V-ribbed belts outer layer of skin, called the Chorion. It is bordered by a thin layer of wax to prevent the egg to dry before the larva has the time to develop fully. Each egg contains a number of small funnel in the form of openings at one end, the micropyles objective of this drilling is to enter the sperm and egg to fertilize. Butterfly and butterfly eggs are in size between species, but they are all either spherical or oval.
Butterfly eggs are on one sheet with a special glue, which quickly hardens. As he hardens are contracts, disrt the shape of the egg. This adhesive is clearly visible to the basis for all the eggs form a meniscus. The type of adhesive is unknown and is a topic for research. This also applies adhesive is a puptoe to the bristles of the cremaster. This adhesive is so difficult that the carpet made of silk, in which the bristles are glued, not be separated.
The eggs are usually on the plants. Each type of butterfly has its own series and hostplant, although certain species of butterflies are limited to a single type of plant, while others use a variety of plant species, many of the members of a family.
The egg takes a step few weeks in most butterflies, but pondus eggs near the winter, particularly in regions of temperate climate, a period of Diapause, and the flourishing of May until the spring. Other May butterflies lay their eggs in spring and they arise in the summer. These butterflies are usually northernly species (cloak of mourning, turtle)

The larvae, or caterpillars, are multi-legs diet of the machines. They consume the leaves and plants spend almost all their time in search of food. Although most caterpillars are herbivores, some species such as Spalgis epius and Liphyra brassolis are entomophages (eating insects). Some of the larvae, especially in the form of mutual Lycaenidae associations with ants. They share with the ants with the vibrations through the substrate and the use of chemical signals. The ants, a degree of protection and their larvae this round to collect the secretion of honeydew.
Caterpillar maturity through a series of steps, called instars. At the end of each phase, the larvae go through a process apolysis, the Cuticula, a mixture of chitin and specialized proteins, is exempt from the shell and the skin begins to form a new cuticle under. At the end of each phase, the larva of the old Cuticula Slough, and the new cuticle quickly hardens and pigments. The development of butterfly wings begins with the last larvae.
Butterfly caterpillars have three pairs of feet true segments of the thoracic and up to 6 pairs of prolegs from the segments of the abdomen. These rings are prolegs of small hooks hooks, which help them attack the substrate.
The caterpillars have the ability to swell the parties to the head to appear as the snake. Many consider false points. The caterpillars have osmeteria structures, the smell everted produce chemicals. These are in the defence.
Guests plants often have toxic substances into the chains and are able to intercept these substances and store in adults. This makes it inconvenient to make the birds and other predators. This unpalatibility is known, with a bright red, orange, black or white warning colors. Toxic chemicals in plants are often designed to prevent insects are eaten. Insects in turn, the development of countermeasures to use or toxins to their own survival. This "arms race" has led to the coevolution of insects and plants, their guests.
