What is an Insect

-Insects have a segmented body divided into head, thorax, and Abdomen

-They have an exoskeleton and three pairs of legs attached to the thorax

Responds to Stimuli

-Insects use many sense organs to detect stimuli

-Compound Eyes, the brain

-Insects have chemical receptors for taste and smell

-They have hairs that can detect movement

Feeding and Movement

Adaptations for feeding

-Insects have three mouthparts for feeding including mandibles

Movement and flight

-Insects have feet that are used for walking jumping and many other things

-Insects ability to fly has allowed them to move all around the world and live in a variety of habitats


-The growth and development of insects usually involve metamorphosis, which is a process of changing shape and form. Insects undergo either complete metamorphosis or incomplete metamorphosis

-Incomplete metamorphosis look very much like adults they are the immature form of insects

-Nymphs lack functional sexual organs and other adult structures like wings

-Complete metamorphosis many insects go through a complete change in the body during this process

-They then undergo a final change where they change into a pupa where they change from larvae to adult

Insects and Humans

-Many insects are known for their negative effects, termites eating wood, bees and wasps stings

-Mosquitos, Desert Locusts destroying crops

-Insects are very helpful though One third of the food we eat depends on the pollination on insects like bee's

Insects Communication

-Insects communicate using sound, visual, chemical, and other signals

-The most important part of their communication is finding a mate male crickets rub their wings

-Some use visual cues like fireflies bling their light to attract females

-Some use chemical signals like moths release a chemical to attract distant males these are called pheromones which are specific chemicals that affect the behavior of other individuals of the same species

Insect Societies

-Many insects such as Ants, Bees, and Termites form complex associations called societies

-A society is a group of closely related animals of the same species that work together for the benefit of the whole group


-Within a society each individual might be chosen to perform individual tasks these are performed by groups of individuals called castes

Communication in Societies

-A specified form of communication is crucial in the working of societies

-Each species of insects has it's own language

-For example when a worker ant finds food she leaves behind a trail of pheromones so other ants can follow it
