How do butterflies reproduce??????????
461250
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.

Being an immature stage of development the reproductive organs are likely to be undeveloped too, ie no point in wasting energy on something not being used!?\n In contrast adult male and female butterflies and moths have well developed genital organs.

None of the above.  Just as you move your arms, so the butterfly moves its wings.

Bulbs can reproduce in two ways. One being bulb increment. That is where the bulb grows to a rather large size and then splits into one or more new BULBETTES which are fed from the MOTHER bulb. These BULBETTES then continues to grow with the MOTHER bulb forming a new plant with the ability to sustain itself (eventually). The second way in which a bulb can reproduce is by seeding. When the flowers bloom they are then cross-pollinated like any other plant and the seeds begin to form

Hope this sheds some light on it jessica.\n\n\nREPRODUCTION\n\nMost fishes are egg-layers, but many bear living young. Live-bearing fishes may be ovoviviparous, in which the eggs essentially simply hatch within the female, or viviparous, in which the unborn young are supplied nourishment through the mother's tissues. In some ovoviviparous fishes the embryo develops in the egg while the egg is still within its follicular covering within the ovary, and ovulation (or release of the egg) and birth occur at the same time. In other ovoviviparous forms the eggs are released from the protective follicles into the cavity of the hollow ovary, where development continues. In some viviparous fishes the walls of the egg follicle are in intimate contact with the embryo, supplying it with nourishment. In the viviparous sharks, a part of the oviduct, or egg channel, is developed into a uterus, where the modified yolk sacs of the young are closely joined to pockets within the uterus.\n\nIn live-bearing fishes and in some egg-layers, fertilization occurs internally, and methods have been evolved for introducing the sperm into the female's body. In sharks the pelvic fins of the male are modified into intromittent organs called myxoptergia, and in the male topminnows the anal fin is modified into a similar-functioning intromittent organ called the gonopodium.\n\nAt least three modes of reproduction--heterosexual, hermaphroditic, and parthenogenetic--are found in fishes. In the most common form, heterosexual reproduction, there are separate male and female parents, but even here there is considerable variation. In some live-bearing fishes, the female is able to store sperm for up to 8 or even 10 months, and this sperm is used to fertilize new batches of eggs as they develop. In some cases, a female may carry sperm from several males at once.\n\nIn hermaphroditic reproduction, a single fish is both male and female, produces both eggs and sperm (either at the same time or at different times), and mates with other similar hermaphroditic fishes. External self-fertilization occurs in one hermaphroditic fish, which sheds egg and sperm simultaneously. In another, internal self-fertilization may occur. In certain fishes there is a time sequence of hermaphroditism, young fishes reversing their sex as they grow older.\n\nIn parthenogenetic reproduction, unfertilized eggs develop into embryos. This is known to exist in at least one fish species, Poecilia formosa, of the Amazon River; however, even though development proceeds without fertilization in some of these females, mating with a male is still required to stimulate egg development.\n\nParental care also shows great diversity. Some fishes, like the Atlantic herring, form huge schools of males and females and freely shed their eggs and sperm (milt), and then abandon the eggs. Other fishes build nests and care for both the eggs and newly hatched young. Others have evolved methods of carrying the eggs with them, commonly in their mouths, but also in gill cavities or in special pouches on the body.

Reproduction is usually sexual. Males are usually smaller than females (often very much smaller) and often have a characteristically bent tail for holding the female for copulation. During copulation, one or more chitinized spicules move out of the cloaca and are inserted into genital pore of the female. Amoeboid sperm crawl along the spicule into the female worm.\n\nEggs may be embryonated or unembryonated when passed by the female, meaning that their fertilized eggs may not yet be developed. In free-living roundworms, the eggs hatch into larva, which eventually grow into adults; in parasitic roundworms, the life cycle is often much more complicated.

they reproduce asexually thru budding\nthat is, every daughter cell is an exact replica of the parent cell

Regeneration is when an being regrows a lost limb or other body part. Some lizards can regenerate their tails if they break off. (Although usually smaller.)\n\nPlants reproduce through sexual means, but they do not have sex. (That would interesting.) All that means is two individuals can reproduce which each other, although it is possible for a flower to reproduce with itself.  Pollen is basically their sperm and travels from one plant to another through insects, like bees, and wind. Then the flowers die and they form seeds. Some plants, like pine trees and ferns reproduce with spores, which work in roughly the same way.\n\nIf you're interested in all the techincal terms that I didn't use, check out the source.

They coloration.\nMoths are mostly nocturnal.\nThey have bodies which help to pollinate flowers, so the flowers they lay their eggs on do not fall off.\nA moth will lay eggs on more than one flower.

About this there are three theories. One, basing itself on an archaic Dutch word for butterfly, 'boterschijte' is that this reflects the color of a butterfly's bowel movements. The problem with this, of course, is that other than to\nvoid excess water, butterflies do not excrete.\n\nA second explanation, i.e., that males of the common\nbrimstone butterfly (Gonepteryx rhamni, Pieridae) of England\nare a buttery yellow.\n\nA third theory holds that, in medieval folklore, butterflies\nwere believed to be disguised witches or fairies who stole\nbutter from pantries and churns. The belief in butter-stealing fairies still existed in England at the time of Shakespeare

Sea cucumbers can reproduce either asexually by budding or sexually by releasing gametes into the water.  Check out Wikipedia...they have some basic info.

It depends on the insect. Some die off leaving eggs behind to hatch next season (like the Praying Mantis). I have heard some critters replace the water in their bodies with glycerin so they don't freeze during the cold months.

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

All animals release pheromones, or perfumes, that attract others, show dominance, etc. So insects attract others this way and then mate. While the fertilization is the same, the mating process is different for many insects. However, many times the female may eat the male.

Well, the most common moth is the Luna moth (Actias luna)\n\nThey only mate and reproduce -- because of this they only live about a week.\n\nAt approximately 10:30 pm (as early as 9:00 pm in early spring) the female moth extends a scent gland from the posterior of her abdomen and begins releasing an air borne pheromone. This scent attracts the male.\n\nOnce coupled, the pair will remain that way until the following evening. In captivity siblings will mate readily, even in a small cage. Wild males are easily attracted. Scenting or "calling" usually continues until around 1:00 am or until the female has mated, whichever comes first.\n\nMales usually emerge a day or two before females and it is rare that an unmated female would be captured at a light as females usually don't fly until after mating. \n\nHope that helps!

They don't. Simple answer. Some might, but most don't - otherwise how would the population ever increase? If there are only ever a set number of nests then all the newborn swallows from last year will always need to find new nests... taking over nests from last year too if they come back early enough / making new ones themselves.

It can die if touched too much.  When touched by humans, the wings tend to lose some scales. If too many scales are lost, the butterfly's ability to fly will be impaired. The scales on the butterfly wings have many properties, mostly optical.  Butterflies are very fragile & best viewed by sight & not by touch.
