1. Characteristics of insects
Three part body – head, a thorax and an abdomen

2. Insects - Entomology
The study of insects

3. What is an insect?
Take 3 minutes to come up with a list of insects, and the characteristics of those insects.
the things that make an insect an insect

4. Characteristics of insects
Have an exoskeleton – made of chitin
Hard, protective, doesn’t grow or change
Three part body – head, a thorax and an abdomen

5. Several mouthparts – most have 3 pairs Three pairs of legs (adults)
Sensory antennae
Several mouthparts – most have 3 pairs
specialized eating
Three pairs of legs (adults)
Specialized for walking, jumping, grabbing
One or two pairs of wings
Differing flying abilities

6. Metamorphosis
Incomplete – the young resemble the adults except with different body proportions

7. Metamorphosis
Complete –
Larval stage looks much different than adults stage.
Larval stage is focused on eating and growing. Adult stage is focused on dispersal and reproduction

8. Woolly Bear Caterpillar

10. Breathing Use muscle contraction to get the air in
A series of tubes called the tracheal system and holes called spiracles for air intake
Use muscle contraction to get the air in
Oxygen moves into the cells via diffusion
Effective for small animals, but not for anything much larger than an insect

14. Insect Societies – “Social Insects”
Some insects form colonies – specifically societies
Dependent on one another for survival
Division of labor – different groups serve different purposes

15. Social Insects

16. Why should we care about insects? How do they benefit humans?
Take 2 minutes to discuss with someone nearby about how insects can be beneficial to humans.

17. Why should we care about insects? How do they benefit humans?
Food – honey
Insects are the primary source of protein in many places Y

19. Why should we care about insects? How do they benefit humans?
Food – honey
Insects are the primary source of protein in many places
Pollination
Critical for most of our food sources
Silk – from the cocoons of the silk worm – up to ½ mile long
Natural and Biological Control – mosquitos, wasp/gypsy

20. Why should we care about insects? How do they benefit humans?
Aesthetics – some insects very pretty
Drawn as art, used as art
Products
Dyes, Polishes, Bees wax
Genetics
Fruit flies used in genetic research because of quick reproduction rates and share 75% DNA with humans
