Butterflies are insects of the family of the arthropoda of the order of the lepidoptera and I can say that they are flying insects , thanks to a pair of wings that boast bright colors and that adorn and fill with joy the environment.

There are nearby 18 000 species worldwide and they can be found even around the Arctic, although only a few species can survive there, but usually they are migratory species in this icy area of ​​the planet.

Butterflies eat nectar from flowers where they get sugars to get energy, although some can eat from nourishment from pollen, sap of trees and rotten fruit. Adult butterflies drink liquids obtained from damp patches to keep moisturized through their proboscis, which is a tubular feeding and sucking organ. Some butterflies require more sodium than nectar can provide, so it is common that they pose on person's skin and drink human sweat which is provided with salt.

Butterflies use their antennae to detect the movement of wind and aromas that are scattered around, so they are covered with sensory organelles known as sensilas. Most of butterflies have a very special sense of taste, they are actually more than 200 times more sensitive to sugars than humans, chemo-receptors located across their body that work only to determine whether the offspring of an insect Many butterflies use chemical signals known to be pheromones, and specialized scales to determine the location of the eggs. receptive females.

One of the reasons why it is worthwhile to study the butterflies is the understanding of their interaction with plants and pests that allow the balance of the environment, what scientists have called co-evolution which is part of the process of organic diversification.

Despite its beauty and its apparent fragility, they have developed mechanisms of defense that have allowed them to survive in the environment. One of the methods is camouflage or cryptic coloration that allows you to look like or leave on the bark of a tree to hide from predators.

Scientific research on coastal dunes of Mexico: origin, evolution and challenges - ScienceDirect
Veracruz stands out as the coastal state with the highest number of sites studied (86). Research shows anthropogenic development as the main stressor on dune ecosystems.

Another method is the Chemical Defense , which has been developed for purposes of survival, secreting chemicals that are toxic to other species.


Butterflies the larvae.

The Caterpillar or larva is considered to be the next stage, in which appears worm with streaks or colors that make them distinctive, and emerge on the sheets where put the egg, which devour during its growth. The chrysalis is the stage of transformation of the worm its way into insect, during which the caterpillar tissues are rolled back to give passage to the adult structures of the insect that is already formed inside. In the majority of species, the chrysalis are brown or green since this color serves as the camouflage in the natural environment.

Once the chrysalis opens, it exits to the butterfly that is usually colorful and is able to fly, reproductive stage. In adulthood the butterflies can live from one week to one year, depending on the species.

They may have one or more cycles of offspring during the year, and some studies show this variation is due to climatic factors, since it has been found to be a tendency of a higher rate in tropical regions than in temperate regions. >

There are other butterflies with nocturnal habits or smaller known moths, even though they may have bright colors in a peculiar beauty, but the fact that they are able to destroy the wood or clothes, make them less attractive insects. p> If you want to see more pics of butterflies, please feel free to click here:
