1.  Metamorphosis- a change in form from one stage to the next of an insect  Larva-worm like stage of insects  Pupa-stage where insect turns from larva to adult  Nymph- a young insect in stage where it looks like a young adult  Chrysalis- another name for pupa stage  Molt- shed  Instars- larva stages

2. Lesson 6 Notes SCIENTIFIC NAME : Pieris rapae

4. EEgg NNymph AAdult

5.  EGG  A female insect lays eggs  Eggs are often covered by an egg case which protects and holds them together

6.  NYMPH  Nymphs do look like small adults, but usually don't have wings.  Nymphs molt (shed) their exoskeletons and replace them with larger ones several times as they grow  Most nymphs molt 4-8 times.

7.  ADULT  Insects stop molting when they reach their adult size.  By this time, they have also grown wings.

8.  Egg  Larva  Pupa  Adult

9.  EGG  The female lays eggs  Usually found on the undersurfaces of leaves.

10.  LARVA  Larva hatch from the eggs  Do not look like adult insects.  Worm-like shape.  Larvae molt several times and grow slightly larger.  Caterpillars, maggots, and grubs are all just the larval stages of insects

11. PPUPA LLarva make cocoons around themselves. DDon't eat while inside their cocoons AAlso known as Chrysalis DDormant during pupa stage TTheir bodies develop into an adult shape with wings, legs, internal organs, etc. TThis change takes anywhere from 4 days to many months.

12.  ADULT  Inside the cocoon, the larvae change into adults  After a period of time, the adult breaks out of the cocoon.

13. A. Process called Metamorphisis i.a profound change in form from one stage to the next in the life history of an organism ii.Temperature effects how quickly metamorphosis occurs B. Egg  Larva  Pupa  Adult i.Pupal Stage also known as Chrysalis ii.Dormant during pupal stage

16. A. L1-L5 B. Determined by taking head measurement C. Eats Mustard Family (EX: WFP) D. Molts 2-3 times in first week of hatching E. L1 i.Larva chews way out of egg ii.Head grows slowly as body grows large F. L2-L5 i.L4&L5: Most eating occurs here

21. ADULT

22. A. 3 part body i.Head, thorax, abdomen B. Proboscis: mouth; take in water and nutrients i.Length varies between species and types of flowers that are their primary food source C. Antennae: sensory structure to find food D. Hair-like structures: sense of taste E. Claws: to cling to surfaces F. Scales: pigment and insulation G. Spiracles: Facilitate gas exchange

25. A. Sexual Reproduction i.Requires male and female parent B. Males: i.1 black spot on inner wing C. Females: i.2 black sposts on inner wing ii.Abdomen larger than males to hold eggs

27. A. Silk glands in head i.Used to attach to surfaces B. Frass: waste i.Used as fertilizer C. Open Circulatory System D. Floral nectar primary food source E. Exoskeleton color due to amount of sunlight CWB is exposed to

28.  Adults can emerge from pupa in 1 minute  Wings take 15 minutes to expand  Wings take 1-2 hours to harden so they can fly

30. Let’s take Professor Know-It-All’s Quiz and see what we have learned!

35. - Name the stages in complete metamorphosis. 1. Egg 2. Larva 3. Pupa 4. Adult

36. Identify the cycle as complete or incomplete metamorphosis.

38. Identify each stage of the complete metamorphosis of the butterfly. A B C D E F

39. Identify the lifecycle of the frog as complete or incomplete metamorphosis.

40. Complete: The baby does not look like the adult. Incomplete: the baby looks like the adult
