Why do butterflies need their color?

Many butterflies have patterns that mimic other things.  For example, there are some with large "dots" on their back wings...These look to predators to be the eyes of a larger animal, which causes the predators to look for another meal.\nOthers have bright colors that imply poison...Some butterflies are really poisonous to predators, and some use the color to scare the predators away.

You know if it's the right one by the way you feel when you are with that person.  However, that might not mean butterflies.  You want to spend time with them all the time, you ask for their opinion on different subjects, you consider them your best friend.  It's the right one if you can't imagine your life without the other person, and you are a changed person because they are in your life.  It's the right one they make you the happiest person in the world and you can't wait to spend the rest of your life with the person.  The butterflies will fade, yes, but the feeling of love remains.

Some Butterflies do have a very short lifespan but not 1 day, unless killed. Remember their main role in the life cycle is to breed and lay eggs. Most Butterflies can achieve mating and egg laying within a in a  10 - 14 day period and would die soon after. Males usually die a couple of days earlier than the female Other Butterflies, particularly the fruit eating ones, have a much longer adult life span of sometimes weeks and months. The Monarch Butterfly is a migratory species and the adult life span is approximately 9-10 months.

I would think that things gradually evolved over time.  There must have been enough "almost" butterflies to pro-create with the butterfly to have offspring.  So I feel it would be like being in the current of the stream and the stream would have kept pushing forward maybe a little different but in the same general direction.  Just a guess..  Good question.

Flower petals are bright colors to attract bees and other insects. the bright colors lure the insect into the flower in which they pollinate the flowers. without the bright colors to attract the insects the flowers would have to seek other means to pollinate and reproduce.

Flowers which change color often do so based upon the acid or base content of the soil.\n\nThis might be the situation in your case.

Nobody really knows. There are many possible reasons why moths are attracted to light but the most obvious is that many moths use the moon to navigate at night. By keeping the moon in a particular position the moth can fly in a straight line and in the direction it wants. Unfortunately moths confuse bright lights for the moon and when they get close to the light they can't navigate properly and end up flying round and round in circles.

They are bright because they have pigment molecules in their petals that absorb particular wavelenghts of visible light, making them appear colored.\n\nBut the reason they evolved those pigments was to attract pollinators.

several butterfly species hbernate over winter and re-emerge in the spring to mate and lay their eggs.\n\nIn the US I believe the Monarch butterfly is a species which hibernates.\n\nIn the UK there are four species that do this. they are the Brimstone, the Comma, the Small Tortoiseshell and the Peacock butterfly.\n\nI've inlcuded some links with more information below:-

Some Dude is correct.  Red coloration is attractive to birds.  Red fruit get's eaten by the birds and the fruid seed passes through the birds digestive tract to hopefully grow up in it's new location.\n\nThe flowers that are normally pollinated by birds instead of insects are usually red, to attract their pollinators.

You could have looked this up... here are some sites, but I recommend the book Invertebrates by Brusca & Brusca; it has excellent and clear illustrations.\n\nhttp://bugs.bio.usyd.edu.au/Entomology/ExternalMorphology/imagePages/mouth_butterfly.html\nhttp://www.enchantedlearning.com/bgifs/Bflyhead.GIF

If you see two adult butterflies with their abdomens linked tail-to-tail, they are mating. The male grasps the female and deposits a sperm packet, which fertilizes the female's eggs. The butterflies can fly while mating, but they usually avoid moving unless they are disturbed. \n\nButterflies and moths undergo complete metamorphosis in which they go through four different life stages. \nEgg - A butterfly starts its life as an egg. \nLarva - The larva (caterpillar) hatches from an egg and eats leaves or flowers almost constantly. The caterpillar molts (loses its old skin) many times as it grows. \nPupa - It turns into a pupa (chrysalis); this is a resting stage. \nAdult - A beautiful, flying adult emerges. There is no growth during this stage. This adult will continue the cycle and reproduce.

There are very big differences depending upon species.\nMonarch and Red Admiral butterflies live long enough to migrate.\nSome butterflies hibernate, e.g. Red Admiral.\nThere are many species that can only survive the Winter as dormant pupae.\nSometimes there can be two or three complete life cycles within a season.\nOccasionally the life span of the imago (the 'butterfly') is indeed very short but remember that insect life cycles involve:\negg - larva (caterpillar) - pupa (crysallis) - imago.\nGenerally, only the pupal stage overwinters.

they are actually bugzappers to get rid of unwanted bugs or flies in restaurants and stores. they have a heating metal rods around the blue colored fluorescent light. the light is to attract the bugs/flies and once they get near the light, they will be toasted by the heated metal rods/cage.

Mammals don't see colors the way we do, for example it may be impossible to train them to choose one of two colors to get a food reward.  Insects often see UV light, which we don't, so two red flowers that look exactly the same to us could look 'great' due to UV markings and 'boring' due to no UV markings to an insect.

Zoologists used to believe that the stripes act as a camouflage mechanism or that they play a role in social interactions, with slight variations of the pattern allowing the animals to distinguish between individuals. However, more recent experiments have led them to believe that the disruptive coloration is an effective means of confusing the visual system of the blood-sucking tsetse fly.
