Information about Insects and Invertebrates
Insects (Class Insecta) are a major group of arthropods and the most diverse group of animals on the Earth. With over a million described species of insect that's more than all other animal groups combined.
Insects are found in nearly all environments on the planet. There are approximately 5,000 dragonfly species, 2,000 praying mantis, 20,000 grasshopper, 170,000 butterfly and moth, 120,000 fly, 82,000 true bug, 360,000 beetle, and 110,000 bee, wasp and ant species described to date. Estimates of the total number of current species (including those not yet known to science) range from two million to fifty million with newer studies favouring a lower figure of about six to ten million. Adult modern insects range in size from a 0.00547 " fairyfly (Dicopomorpha echmepterygis) to a 21.9" long stick insect (Phobaeticus serratipes).
