Butterflies moths belong to the evolutionary tree. Their origin was established in peioada Cretaceous, which ended after 65 million years. Unfortunately, there is very limited fossil archive.
The oldest fossil is a possible skipper butterfly, unnamed in the upper Paleocene period (about 57 million years ago) from Fur, Denmark. One of the most beautiful preserved is Riodininae (Voltinia dramba) last 25 million years, found in amber from the Dominican Republic.
Butterflies are currently distributed worldwide, except very hot and arid regions. It was estimated a total of 17,500 species of butterflies (Papilionoidea) of a total of 180,000 species of Lepidoptera.
Butterfly silk is an important insect species of economic and belongs Fam. Bombycidae, Ord. Lepidoptera. Several varieties or races. Races in our country, with an evolutionary cycle generated a year are monovoltine. In other countries there are races 2-3 or more cycles per year and are called polivoltine.
Voltinismul is a biological phenomenon characterized by the production of a generation, or more, in the course of a year. Hereditary character is being influenced by external environmental factors (light, temperature, humidity).
For a long time, the butterfly silk was domesticated and raised in China. Today it is thought that his ancestors are species Bombyx mandarin and Theophilos religiosae, living in China, the two Koreas and Japan. It shows the great importance for the economy as larvae, known (incorrectly) the "silkworm" produce silk threads.
Butterflies feeding on colorful flowers with a strong smell.
Most of these flowers are her red, orange or pink colors they can see well.
The butterflies feed on nectar, a sweet liquid found in the majority of flowers, which we extracted through the tube, by inserting the flower.
The flowers produce nectar to attract insects only.
The butterfly body is covered with fine julienne. The head, ovoid, big eyes towards the two antennas pinnate using smell and touch. The device is rudimentary mouth, and the gut atrophy. Thorax are inserted two pairs of wings.
The abdomen is made up of nine segments. The male and liveliness can be recognized by the presence of abdominal segment 8 on the dorsal surface of a chitinous curved plates, which protects the abdomen segment 9. The female is bulky.
The five families of true butterflies, known usually Papilionoidea superfamily are:
- family Papilionidae
- family pieridae
- family lycaenidae
- family Riodinidae
- family Nymphalidae
After mating, the female lays hundreds of eggs (500-800). Butterflies die generally 8-12 days after mating. The eggs are elliptical, light yellow color. If the egg is fertilized, change color becoming orange-yellow, pink-gray, with different shades against the races (European, Chinese, Japanese).
Unfertilized eggs remain yellow. When eggs from different races bi- or polivoltine color remains yellow up close to hatching, they become darker. In diapause eggs have a gray color.
Evolutionary cycle runs passing through stages known complete metamorphosis: egg, larva, nymph and adult. After laying eggs in egg embryo is formed in about 3 days. In bad times (summer) enter diapause eggs breeds temperate zone. The eggs are placed in an incubator, where the larvae hatch after about 11-14 days of age first (I) has 5 .Stadiul larval growth phase is also called the "Age".
Each stage is separated from the next by a period of rest, called the "sleep". 24-48 hours before moulting larvae stop feeding and and fixed to a substrate that sit idle until the shed. During sleep, the period of preparation to moulting, halls ecological factors in growth must be modified by sericulturist: high temperature by 1oC; low light; Do not give food; do not change the bedding. Important is that the larvae will not be disturbed, because otherwise they die.
Larval stage lasts about a month, with some variation depending on the breeds worms and growing conditions. At the end of 5th larva age measuring 6-7cm in length, with a weight of 5-6g.
Larvae of Bombyx mori have made the body of the head, thorax and abdomen skin covered by a chitinous, in the early stages blackish color. With increasing color becomes milk. In the region of the chest are three pairs of legs and the underside of the abdomen are more pairs of false legs.
Appeared broken and chewing mouthparts type (labrum, labium, two mandibles, two maxillary and two Palpa Palpa labialis). It should be noted that a different part of the digestive tract and have 2 sericigene glands which, after joining them in the cephalic region, are opened by a hole (chain) below labium.
Towards the end of the larval period V, the larvae stop feeding and looking instead for ingogosare (hatching cocoon). For this purpose, after the vegetable is fastened to the supports (strains of mature, canola, oak branches) they secrete silk thread through a die to form "donut". Thus, within the donuts close larvae transform into the chrysalis (nymph) in about 6 days.
Nymphs are oval, real estate, do not feed. In 10-12 days nymphs turn into adults. In the life cycle of the butterfly silk is found diapause (resting) phase which is installed in the egg after 3 days from the clock. Indigenous breeds diapause lasts 9-10 months, from July through April.
Did you know that:
The biggest diurnal butterfly in the world is the butterfly Ornithoptera alexandrae New Guinea? He has the wingspan of 32cm.
Variegated butterfly got its name from Englishman Lady Eleanor Glanville.
Butterflies have a GPS type system in antennas.
Butterflies taste with their legs.
Butterflies live one day.
vButterflies can be seen in paintings of Egyptian tombs and medieval paintings, Chinese, Silk and modern art on canvas.
