📚 Part 1: Knowledge & Data Interpretation

1. Match each life stage to its correct order number (draw a line):

A. Egg

B. Adult (butterfly)

C. Larva (caterpillar)

D. Pupa (chrysalis)

2. Which stage is primarily responsible for feeding and growth?

Egg

Larva (caterpillar)

Pupa (chrysalis)

Adult (butterfly)

3. Check all environmental factors that commonly reduce butterfly populations:

Climate change (temperature and seasonal shifts)

Increased predation by birds

Habitat loss and fragmentation

Short-term gusts of wind

4. Data analysis: Two meadows were surveyed for adult butterflies this month. Meadow A counts: 12, 15, 14, 16, 13. Meadow B counts: 8, 9, 10, 7, 11. Which meadow has the higher median? Show your work.

✏️ Part 2: Short Answers & Analysis

5. Fill in the blanks: Put the four life stages in order from first to last.

Egg → _________ → _________ → _________

6. Explain in 1–2 sentences how cellular differentiation contributes to metamorphosis in butterflies (connect to HS-LS1-4).

7. Based on the meadow data (Question 4), propose one specific conservation action to support butterfly populations and explain how it addresses a factor you checked in Question 3.

8. Exit ticket (one sentence): Why is monitoring butterfly populations useful for assessing ecosystem health?
