Why are hemiptera, dunata, and isoptera inconplete metamorphosis if for example dragonflies have larvae?

That's just the way it is, student. Each has evolved according to its needs in its environment. Metamorphosis means 'change in form'. Most insects undergo this change, sometimes along with a change in habits and needs, to a greater or lesser degree, at some point in their lives. The change occurs during molting, when the exoskeleton becomes too small, splits, and is shed. This is the complete list of insects that have incomplete metamorphosis. Homoptera: Aphids, Cicadas, Preying Mantis Dermaptera: Earwig Thysanoptera: Thrips Odonta: Damselflies, Dragonfly Plecoptera: Stonefly Isoptera: Termites Psocoptera: Bark Lice, Book Lice Mallophaga: Chewing Lice Anoplura: Sucking Lice Collembolla: Springtails and Thysanura :silverfish have no metamorphosis. http://members.aol.com/KSmith9526/InsectOrders.htm This site gives more detail on metamorphosis. http://www.caf.wvu.edu/~forage/4002.htm Feb 11 03, 2:27 AM

WAIT!!! Odonta: Damselflies, Dragonfly Plecoptera: Stonefly HAVE metamorphosis! dragonfly larvae live in the water and are those weird things with the weird botom jaw that extends and grabs things! damselflie larvae look pretty much the same but they don't have wings and they live underwater and they have tails! stoneflies are like damselflies!
