Insects include the greatest number of species of
any class of animals. They have been divided into thirty Orders.
However only four Orders of insects consist of species whose
larval forms are always aquatic, while another nine Orders
contain some species with either aquatic larvae or which are
aquatic throughout larval and adult stages.
Insects are characteried by a hard, segmented,
exoskeleton and by a three segmented thorax, each bearing a
pair of legs and usually with two pairs of wings attached to
the second and third thoracic segments. In the Diptera and
some mayflies (Ephemeroptera) the wings are reduced to a single
pair, while in primitive insects such as springtails and silver
fish, wings are absent. They have also been lost from some
species of more advanced orders of insects.
