How many insects are there on Earth? Estimates on the number of total insects species fall as high as 30 million and as low as 2 million. The estimate that many people agree upon is about 5 million, so biologists have yet to identify more than 80 percent of the estimated total number of species [source: Hogg].

Cockroaches (Roaches) There are 4,300 known species of cockroaches worldwide, and more are discovered all the time. Seventy of those species call North America their home. Out of all the species in the world, only around 30 to 35 are considered pests.

- Estimates of the total number of insect fall in the range of 1 to 30 million. The vertebrates represent the remaining 3% of all species and include species that are the most familiar to us: amphibians, reptiles, birds, fishes, mammals.

- More about new species: 1  In 1833, British entomologist John Obadiah Westwood estimated there were 400,000 species of insects. 2  Scientists have been discovering new species at about the same pace since 1758.  As many as 10,000 species of undiscovered bacteria are thought to be present in one scoop of soil.

How many insects are there in the world? In the top 9-12 inches of grassland soil in England (an area of very low insect diversity compared to, say, the Amazon), the estimates for arthropods (including mites and springtails) are up to several hundred million individuals per acre, and 1/3 to 1/10 of that are insects proper.

How many species of insects are there on Earth? Numbers of Insects (Species and Individuals) It has long been recognized and documented that insects are the most diverse group of organisms, meaning that the numbers of species of insects are more than any other group. In the world, some 900 thousand different kinds of living insects are known. This representation approximates 80 percent of the world's species.

What is an Insect? The class Insecta, or insects, are the Arthropoda that have three pairs of legs, a segmented body divided into three regions (head, thorax, and abdomen), one pair of antennae and, usually, wings. Other Arthropoda classes have more than three pairs of legs and only one or two body regions, and they never have wings.

- There are more than 800,000 species of insects on earth, more than all the other plants and animals combined. Of this great number of insects, nearly half are beetles. Unlike other insects, beetles have a pair of leathery protective wings called elytra that cover their membranous flight wings. During flight, the elytra are spread apart and the two flight wings are unfolded and extended.

Other Types of Flies There are approximately 120,000 species of flies that have been described by science. The actual number of species in the world is likely to be much larger. Species of flies are grouped into genera and families.

- 1. There are more than 11,000 species of moths in the U.S. alone. Moths outnumber butterflies, their nearest relative, by more than 10 to 1, said Matthew Shepherd, communications director and senior conservation associate at the Xerces Society, a nonprofit organization focused on insect conservation in Portland, Ore.

Insect New species of insects are continually being found. Estimates of the total number of species range from 2 million to 30 million. Insects have six legs; and most have wings. Insects were the first animals capable of flight. As they develop from eggs, insects undergo metamorphosis. Insects live all over the planet: almost all are terrestrial (live on land).

- In the United States alone 30 kinds of the Botfly species have been found. To name a few are the Mouse Bot Fly, Horse Botfly, and the Human Botfly. The bot fly will hijack a mosquito to inject the host with the eggs. It latches onto several species which allow the larvae to enter the skin of the host.

How many insects are there in the world? But if we have, let's say, 10 million individal insects per acre of land, and earth's surface area of land is 36.48 billion acres, that's 364,800,000,000,000,000 insects in the world. If we estimate about a hundred million insects per acre, we're now looking at numbers in the quintillions.

How Many Species? A Study Says 8.7 Million, but Itâs Tricky in 1833 a british entomologist named john obadiah westwood made the earliest known estimate of global biodiversity by guessing how many insect species there are he estimated how many species of insects lived on each plant species in england and then extrapolated that figure across the whole planet

How many insects are there in the world? Insects also probably have the largest biomass of the terrestrial animals. At any time, it is estimated that there are some 10 quintillion (10,000,000,000,000,000,000) individual insects alive. In the United States, the number of described species is approximately 91,000. The undescribed species of insects in the United States, however, is estimated at some 73,000.
