2. Insects
Arthropods (segmented body, exoskeleton, and jointed appendages)
Invertebrates
Insects

3. Insect Anatomy 3 body segments
Head – with a pair of antennae and two eyes (usually compound- effective at detecting movement)
Thorax – with 6 legs and usually 2 pairs of wings
Abdomen – contains most of the insects organs
Contains small tubes that allow air to enter the body; oxygen then travels directly to the cells.

4. Insect Anatomy
Exoskeleton – outer covering (made of protein and chitin) that supports and protects the body

5. Insect Nutrition Nutrition – various diets for different insects:
Plants/plant products
Animals (ex. fleas and mosquitoes)
Decaying animal bodies (ex. Carrion beetles) or animal waste (ex. Dung beetle)

6. Insect Feeding Mouthparts are adapted to type of food:
Butterfly has long tube to “drink” nectar
Ants have sharp mouthparts for cutting wood and seeds

7. Insect Senses Good senses (in addition to compound eyes)
Chemical receptors on mouthparts, antennae, and legs to detect taste and smell
Hairs on legs detect slight movements in air or water

8. Insect Life Cycles Development (life cycle)- metamorphosis- two types:
Incomplete (ex. Grasshopper)
Egg  nymph  adult

9. Insect Life Cycles Complete (ex. Butterfly)
Egg  larvae (caterpillar)  pupa (cocoon)  adult (butterfly)

10. Beware the Bot Fly!
Bot flies use mosquitos to carry their eggs to a host. The mosquitos inject the host with the eggs. Eggs grow to maturity underneath the skin.
