![]() ![]() Most insects have either gradual or complete metamorphosis. Complete Metamorphosis - 4 (egg, larva, pupa, adult).Incomplete Metamorphosis - 3 (egg, naiad, adult).Gradual Metamorphosis - 3 (egg, nymph, adult).No Metamorphosis - 3 (egg, nymph, adult).The types of metamorphosis, with the number of stages in each, are as follows: While most insects begin life as eggs, there are four different paths, or type of metamorphosis, that will allow an insect to reach the adult stage. This ability to change has allowed insects to specialize and fill a wide variety of roles in the environment. Metamorphosis, or change in form during development, is one of the distinctive features of insects. An insect goes through its life cycle more rapidly at 85° F than it would at 70° F. Insects are cold-blooded, so their activities are regulated by temperature. ![]() Most insects don’t grow after they reach the adult stage. Only insects in the most primitive orders grow and molt after becoming adults. Depending on the species, insects may molt four to six or more times as they develop. They feed for a period of time, then molt or shed their external skeleton and begin to feed again. How Do Insects Grow and Develop?īecause their skeleton is on the outside, insects can’t increase gradually in size like humans and other vertebrates. grasshoppers, crickets, walkingsticks, mantids, roaches, termites, lice, stink bugs, assasin bugs, cicadas, aphids, beetles, butterflies and moths, flies, bees, ants, and wasps, plus many other creatures. As mentioned above, insects make up most of the arthropod species on earth, with about 1 million species on earth and 15,000 in Kentucky. Insects will also OFTEN have wings (not all insects have wings, but NO other arthropods ever have wings). three main body regions (head, thorax, abdomen).An insect will have, in addition, these characteristics: To be a member of the Class Insecta, a creature must first be an arthropod (it must have no internal skeleton and it must have paired, segmented legs). An insect is a special kind (or "CLASS") of arthropod. ![]()
