These Days Even Insects Are Advertising Big Companies

Insects are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. They are among the most diverse groups of animals on the planet, including more than a million described species and representing more than half of all known living organisms.

The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing animal life forms on Earth. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, a habitat dominated by another arthropod group, crustaceans.

The life cycles of insects vary but most insects hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages can differ from the adults in structure, habit and habitat, and can include a passive pupal stage in those groups that undergo complete metamorphosis. Insects that undergo incomplete metamorphosis lack a pupal stage and adults develop through a series of nymphal stages.

The higher level relationship of the hexapoda is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22–28 in). The most diverse insect groups appear to have coevolved with flowering plants.

Giant Species Of Insects From New Zealand

Insects (from Latin insectum, a calque of Greek ἔντομον [éntomon], “cut into sections”) are a class of living creatures within the arthropods that have a chitinous exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. They are among the most diverse groups of animals on the planet, including more than a million described species and represent more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing metazoan life forms on Earth. Insects may be found in nearly all environments, although only a small number of species occur in the oceans, a habitat dominated by another arthropod group, the crustaceans. The life cycles of insects vary but most hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts.

Most Beautiful Species Of Mantis

Mantodea (or mantises) is an order of insects that contains approximately 2,200 species in 15 families worldwide in temperate and tropical habitats. Most of the species are in the family Mantidae. Historically, the term mantid was used to refer to any member of the order because for most of the past century, only one family was recognized within the order; technically, however, the term only refers to this one family, meaning the species in the other 14 recently established families are not mantids, by definition (i.e., they are empusids, or hymenopodids, etc.), and the term “mantises” should be used when referring to the entire order.
A colloquial name for the order is “praying mantises”, because of the typical “prayer-like” stance, although the term is often misspelled as “preying mantis” since mantises are predatory. In Europe, the name “praying mantis” refers to Mantis religiosa. The closest relatives of mantises are the orders Isoptera (termites) and Blattodea(cockroaches), and these three groups together are sometimes ranked as an order rather than a superorder. They are sometimes confused withphasmids (stick/leaf insects) and other elongated insects such as grasshoppers and crickets.
The scientific name Mantodea comes from the Greek words μάντις meaning a prophet, and εἶδοςfor form or shape. The name was coined in 1838 by the German entomologist Hermann Burmeister. The common term mantis is also from the Greek word μάντις for prophet.
