SECTION 1



INSECTS




Insect 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 (2228 in). The most diverse insect groups appear to
have coevolved with flowering plants.

ENTOMOLOGY




Entomology, that which is cut in pieces or engraved/segmented", hence
"insect", "knowledge", is the scientific study of insects. Insects have
many kinds of interactions with humans and other forms of life on earth,
so it is an important specialty within biology.

Though technically incorrect, the definition is sometimes widened to
include the study of terrestrial animals in other arthropod groups or
other phyla, such as arachnids, myriapods, earthworms, and slugs.
