they are divided into 30 different Orders (groups) based on mouthparts, wings, and development

Ant Life Cycle
The life cycle of the ant consists of four stages: egg, larva, pupa, and adult. Fertilized eggs produce female ants (queens, workers, or soldiers); unfertilized eggs produce male ants.
Egg : Ant eggs are oval shaped and tiny (they are on the order of 1 mm long, but the queen's egg is many times larger).
Larva : The worm-like larvae have no eyes and no legs; they eat food regurgitated by adult ants. The larvae molt (shed their skin) many times as they increase in size.
Pupa : After reaching a certain size, the larva spins a silk-like cocoon around itself (against a solid object, like the wall of the chamber) and pupates. During this time the body metamorphoses (changes) into its adult form.
Adult : The pupa emerges as an adult. The entire life cycle usually lasts from 6 to 10 weeks. Some queens can live over 15 years, and some workers can live for up to 7 years.
Mouthparts – Structure and Function
insects developed wings to escape predators and to colonize new habitats
wings can provide protection for the softer parts of insects
wings also have changed in size to create fast flight times
Insects taste using their mouthparts and their FEET-some use their antennae
Insects smell using their antennae
Insects touch using small hairs found on their bodies (they can feel wind)
Insects hear using smalls hairs, usually found on their legs
Insects have two compound eyes (for movement, color, and images)
Insects can have up to three simple eyes (see light and dark)
Insects inhabit almost every type of environment except for salt water
They can be found on all continents
They live in plants, wood, living animals, and fresh water
Insects adapt their bodies to the environment that they live in
It is mostly instinctive – instincts are determined by genes before it hatches from an egg
They are programmed to eat certain foods, to defend against attack
Insects do have the ability to learn – identify locations by sight
