The incredible size of individual species of insects is only dwarfed by the incredible numbers they sometimes occur in. In 1943 Profeesor Salt found that an acre of British pastureland near Cambridge supported over 1,000,000,000 Arthropods of which nearly 400,000,000 were Insects and 666,000,000 were Mites the remaining 38,000,000 were Myriapods (Centipedes and Millipedes).Some Scientist have recorded the otherwise inconspicous Springtails at densities as high 100,000,000 per square metre in the ordinary farm soil of Iowa U.S.A. In Africa swarms of Orthoptera ( Desert Locusts Schistocerca gregaria) may contain as many as 28,000,000,000 individuals. Although each Locust only weighs about 2.5grams when they are all added up together this comes to 70,000 tons of locust Ants are social animals and live in colonies, sometimes these colonies may contain only 50 or so individuals, but, one supercolony of Formica yessensis on the coast of Japan is reported to have had 1,080,000 queens
and 306,000,000 workers in 45,000 interconnected nests.
Some Scientist think that 30% of the animal biomass of the Amazon Basin is made up of ants,
and that:-- 10% of the animal biomass of the world is ants,
furthermore they believe another 10% is composed of Termites. This means that 'social insects' could make up an incredible 20% of the total animal biomass of this planet.

Biodiversity by the numbers
According to the GBA, there are 1.75 million recognised species. Other estimates revise this total to 1.5 million species, after accounting for historical errors in taxonomy, and anticipate that another 13,000 new species are added each year.11 That’s the figure for species that have been found, caught, described and formally named. Millions of species exist that are undiscovered. The GBA also set low and high estimates in assessing the total number of species on Earth: 3.6 million and 111.6 million, respectively. The latter figure, dominated by 100 million insect species, is now thought to be extremely excessive; more conservative estimates now put the total around 13 to 14 million.12

i think of i be attentive to what your attempting to declare, for my section no person creature has an greater hand with spirituality and particular we are all equivalent, yet we are the better species,in a feeling of capability and intelligence, so i think of its o.k. to consume meat and stomp bugs...besides the reality that i do no longer stomp bugs..yet yea, meat = tasty and good for us so its a o kay

It depends on what you are really asking. Are you asking for % by numbers, by numbers of species, by mass? Depending on what you are asking, the answers will be different. Google it.
