Free butterfly wallpaper brings the butterflies closer to people through still pictures. Butterflies are such beautiful insects that are fascinating to adults as much as to the little children. There are many different species of this lovely creature all over the world. Some people plant gardens to attract these species out of a strong attachment to these creatures.
However what most people may not realise is that they have a fascinating growth cycle. They start out as eggs. The eggs have a variety of colours depending on the butterfly specie. Some are green, others are yellow and brown among other colours. From the egg comes out the larva which is a caterpillar. Caterpillars are not as beautiful as butterflies such that the transformation of the butterfly in its growth cycle is amazing. From the larva stage the butterfly is transformed into a pupa or chrysalis. At this stage the butterfly is wrapped in a cocoon. It is at this stage that the butterfly metamorphoses from a caterpillar into a beautiful, winged butterfly. Some free butterfly wallpapers depict the growth cycle of butterflies. These can be a complete science lesson for children and adults alike.
Butterflies have a lifespan ranging from one week to one year. During this time they mate in order to reproduce. Once the female lays its eggs the butterfly growth cycle begins again. They have interesting colourations which have been the subject of much study. Colours may be similar to those of plants as a way of protecting these creatures from predators. With many different species of butterflies, free butterfly wallpaper depicts some of the common ones. These show different features and colourations.
Butterfly wallpaper is quite colourful since butterflies are found on flowers and plants in gardens or in the forest. Some of the colours are quite dull while others are bright. People can choose from different colour combinations for their wallpaper.
It may interest you to know that the studies of the design of the wings of these creatures gave rise to the designs of the wings of some aircraft. The interesting colours of the butterflies come from the minute scales which can rub off if touched. The brown and black colours come from the pigments in the scales while the brighter colours such as blue, red and green are created by the microstructure of the scales. Studies of the colours of these insects inspired the development of the light emitting diode.
Some scientists are studying the pigments in these insects so as to develop novel nanosized colour pigments that are non-toxic for various applications. Who knows what having free butterfly wallpaper will inspire you to do? Is it not amazing that a small creature like a butterfly has influenced humanity in such tangible ways?
