THE
WORD INSECT REFER TO small invertebrate creatures,
especially those with bodies divided into sections.Insects ,
including beetles,ants,bees,butterflies,and moths , belong to
various orders in the class insect a, which is a division
of the phylum Arthropods.Features common to all insects
are an exoskeleton (external skeleton), three pairs of jointed
legs , three body sections (head,thprax,and abdomen );and one pair
of sensory antennae .Beetles are the biggest group of insects
, with about 500,000 species (about 50% of all known
insects). They have a pair of hard Electra (wing cases ),
which are modified front wings.The principal function of
Electra is protect the hind wings., which are used for flying
.Ants together with bees and wasps ,form the order Hymenotera
, which contain about 200,000 species .This group is
characterized by marked narrowing between the thorax and abdomen .
Butterflies and moths form the order (Lepidoptera means " scale wings". The separation of the Lepidoptera into butterflies and moths is largely artificial as there are no features that categorically distinguish one group from the other . In general , however , most butterflies fly by day ,where as most moths are night -flyers.Some insects including butterflies and moths under go complete metamorphosis(transformation) during their life-cycle.
A butterfly metamorphosis from an egg to a larva (caterpillar), then to a pupa and finally to an adult butterfly.
