Presentation Transcript

  1. Lets get started! In a group: Create an insect out of the play dough provided. • Be ready to present your insect to the entire class. Include in presentation: # of legs wings Any significant characteristics.

  2. Lesson# 2 – Insect Anatomy

  3. What is an Insect? An insect is an animal whose body is divided into three regions with three pairs of legs on the middle region and contain an exoskeleton. They also have one pair of antennae, and one to two pairs of wings attached to the middle region if present in the adult form.

  4. Break it Apart Look at the insect you have been given. Cut the insect out and into parts the parts you believe it has. When you think you have your insect broken down, call Ms. Masters over to get her approval. Next, glue the parts down in your notes, leaving some space between.

  5. Insect Anatomy

  6. 1. Head Head- contains one pair of antennae, two pairs of eyes, and mouthparts.

  7. 2. Thorax • Thorax- three pairs of legs and wings if present.. • Prothorax - Pair of front leg • Mesothorax – Pair of middle legs and first pair of wings present. • Metathorax – Pair of hind legs and hind wings if present.

  8. 3. Abdomen • Abdomen- the abdomen is composed of as many as eleven segments but never hears legs or wings. • A pair of spiracles are located on each segment of the abdomen. Spiracles are how the insect gets oxygen.

  9. Exoskeleton • Insects have an exoskeleton that is made of material called chitin. • Advantages-protects the insect from enemies, keeps them from drying out, and it protects them from diseases. • Disadvantage-is it is brittle and restricts movement.

  10. Antennae • The antennae are sensory organs for insects, they help the insect in locating food, finding remote nesting sites, and locating mates.

  11. 12 Types of Antennae • Filiform • Setaceous • Capitate • Pectinate • Plumose • Stylate • Moniliform • Ciavate • Lamellate • Bipectinate • Aristate • Serrate

  12. Antennae Types You have pictures of 8 insects Cut out the pictures Paste them to your notes and label the type of antennae they have Once you think you’ve got it, call Ms. Masters over to check

  13. Legs, Legs, Legs There are 6 types of insect legs. Cut out the pictures and leg types Match the picture an leg type Once you think you’ve got it, call Ms. Masters over to check

  14. Types of Insect Legs Running Leg

  15. Types of Insect Legs Swimming Leg

  16. Types of Insect Legs Jumping Leg

  17. Types of Insect Legs Pollen Carrying Leg

  18. Types of Insect Legs Digging Leg

  19. Types of Insect Legs Grasping Leg

  20. Cut and paste What legs? By the leg type

  21. Summarize what we’ve learned! • Insects must have: • # of common mouthparts: • # of antenna: • Number of leg types: 3 body segments, antenna, exoskeleton, 6 legs. 6 common types we discussed. 12 Types of antenna 6 types of legs.

  22. Review Draw and label the insect. Label the 3 main parts, type of antennae, and type of legs.

  23. How do Insects eat? Insect Mouthparts Lab

  24. Which Mouthparts? Group the insects you have been given into groups based upon their mouthparts.

  25. Piercing-Sucking Mouthparts • Aphid • Leafhoppers • Mosquitoes (Females) • True Bugs • Mites

  26. Rasping-Sucking Mouthpart Thrips

  27. Chewing Mouthparts • Grasshopper • Beetles • Dragonflies • Caterpillars

  28. Sponging Mouthpart Flies

  29. Chewing-Lapping Mouthpart • Bees • Ants • Wasps • Sawflies

  30. Siphoning Mouthpart • Moths • Butterflies
