I don't think you could narrow it down to just one, i've seen hundreds of them.lol, good question though.

Although many insects are termed "flies," only those having one pair of wings belong to the insect Order Diptera.  There are more than 110,000 described species of flies in the world.

Ribbonworms belong to the phylum Nemertea. \nThere are 2 classes: Class Anopla and Class Enopla.\n\nThere are also are 2 orders Anopla and Enopla (guess which class each of these goes in!!!!!)

There are about 150,000 described species of flies, you should really narrow down this question a little. Some flies in higher latitudes and higher altitudes can live for a couple years, this is mostly due tothe fact that thier development is typically slower in colder climates. Certain other flies can live only a couple of days

If you begin with a single female, for the first generation, 40 moths will survive (1/3 of 120).  For the second gereration, the 20 females (1/2 of the survivors) will produce 800 surviving offspring (1/3 of 20 x 120), one-half of which are females (400).  Continue the sequence to the 5th generation, then add the total males and females during the year .  Your answer will be  little more than 3 million of each. Note that the original female is not counted as a generation, as she is already an adult at the beginning of the year.  Also, it is assumed that a female lays 120 eggs only, no more and no less.

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.

Insects are defined as the entirety of class Insecta, and there are about 925,000 different species--more than half of all animal species.  Flies are defined as members of order Diptera, which number about 200,000, and they are a subset of insects.  Mosquitoes are members of the family Culicidae, and are also Dipterans, so they are themselves flies.  There are about 3500 species of mosquito.

I have always favored the butterfly opsed to any other insect.  however if to be a butterfly i would have to go through the evolving part i would say know.  I have stepped on many a caterpiller.  oops!  i have a tatoo of a butterfly that used to be a spider.  I callit my spiderfly.  my fiance calls me his iron butterfly.  cause i am strong and yet gental.

There are a lot more than eleven.  Biology texts\noften give details about only the commonest, and\nthey may list ten or eleven of these.  A college\nbiology text will normally at least list all of them, and the\nnumber will very from one reference to another,\ndepending on whether some of them are split up\nor not.  Twentyseven phyla (the plural of phylum)\nhave been recognized by many books, more or\nfewer by others.

That would be absolutely impossible to answer with an exact number.  First, if you mean insect species, there are many that are undiscovered.  If you mean absolute total number of every insect, well, I don't know that anyone could even come close to a real estimate, let alone an actual number.

They say there are over 12,000 different kinds and possibly more that we havent discovered yet. Here is the link...
