There are millions of species of insect in 29 orders. How are there so many? Insects have very fast reproductive cycles. Each insect produces thousands of eggs per female individual. The faster an animal's life cycle the faster genetic mutations can enter the environment and thus the faster they can be selected or eliminated. Divergences and difference-arisings among fast reproducing organisms occur faster than other organisms because of the rapid reproduction. This is the best answer I can give, genetically, evolutionarily and species-divergently.
Additions to this explanation may include that insects are successful terrestrial organisms with a protective chitinous exoskeleton. Does this protect them enough from predators and climates, keeping them alive long enough and numerously enough to evolve rapidly and diversely? Insects have diverse ways of protection, from webspinners protecting themselves in their own web-blankets to ants with stings, catepillars with ingested and self-used poisons, moths' warning flashes of colour and 'false eyes' and bombadier beetles which fire boiling liquid at enemies.
Also, insects are (usually) flying. With this capability there is a great scope for niche occupying in the 3D world flight offers. Single trees at different levels can be captured as niches by different species. Also being so small may increase the scope of niche occupance. Different sorts of fields, rock-crevices, tree levels or any sort of undergrowth or even fresh water are all possible niches for insects, whose surface area is increased dramatically from the insects small-size point of view. With so much area to occupy, niche-divergences could occur at a very fast pace, evolving insects into their hugely multitudinous forms.
Another idea is arms race. Insects may be involved in arms races with plants. Plants continuously adapt to insects devouring them by producing greater and greater varieties and powers of toxins. Insects in response evolve immunities to these toxins and continue to devour unremittingly.
Maybe an extremely powerful force could be plant-insect pollination symbiosis. As the plants evolve differing flower structures, insects (in another sort of arms race) evolve anatomical structures to still be able to acquire nectar from the flowers they seek. The more this goes on, the more plants evolve, the more insects evolve.
Among the phenomenal array of insect species, all, some or none of these specialization-encouraging phenomena could be occurring. Any one explanation for the diversity of insects could be a single one of the above options, a combination or something slightly different that we do not know yet.
Many kinds. These are more primitive and don't pupate from a larva that looks very different from the adult: silverfish, mayflies, dragonflies, damselflies, stone flies, grasshoppers, aphids, cicadas, true bugs, cockroaches, mantids, scorpionflies, fleas.
From here on they metamorphosize and the larva looks very different: flies, hoverflies, mosquitos, wasps, bees, ants, beetles, butterflies, moths, lacewings.
about 1,382,000,000
There are no insects with eyes on their knees. However, there are many kinds of insects with ears on their knees. Some examples include crickets and grasshoppers.
There would be fewer species of insects and fewer insects in general in the yard.
Yes, they are (by definition) considered insects. They are in the insect order Lepidoptera and are classified with insects because they have a head, thorax, and abdomen. They also have three pairs of walking legs, antennae and a pair of wings-which are the characteristics of most insects.
Invertebrates. Butterflies are what is classified as an insect. Insects have no vertebrae; instead they have an exoskeleton.
Insects became resistant because the insecticides were used on the continuously. Most insects will die at first, but there will be some that have the right genetics to resist that insecticide. When that happens the insect will the favorable gene reproduces and creates more insects that are resistant. Humans promoted this evolution by using the same insecticide on the insects.
insects of most kinds
There are many kinds of animals or insects are afraid of light and stay in the dark. These insects include cockroaches.
they do not eat insects they eat plants
more than 800,000
ants
fruit flys and other regular insects
look on google.com at images and type in insects..... You will find all kinds of insects and if you mean where can i find out about insects type in on google Insects and find facts about them.
There are many different kinds of wood eating insects in the state of California. These insects can be found anywhere.
insects such as bees and butterflies
it eat all kinds of fishes and insects to
people can eat all kinds of insects if it is dead for example like callipillers
Arachnids, Crustations, Millipedes, Centipedes, Insects
