Differences between a butterfly and a moth.

Differences between a butterfly and a moth. Hello tutor, could you kindly help with answering the questions below. Thank you

1. Observation: Butterflies range from a tiny 1/8 inch to almost 12 inches. Millipedes coil their bodies into a spiral when threatened. Ladybugs play dead to protect themselves

Question: 

What are the physical differences between a butterfly and a moth?
Repeat the question, list possible explanations (Hypotheses)

2. Observation:

Ants use different pheromones that lead to food sources and back to the colony. Many bugs replace the water in their bodies with a glycerol that simulates the effects of anti-freeze to prevent freezing in winter. Only honeybees die when they sting you.

Question:

Why are insects, like moths, attracted to light?
Repeat the question, list possible explanations (Hypotheses)

3. Discuss the question, “Why do beetles have elytra (the hard forewings of beetles) instead of membranous wings?”
List at least 2 possible explanations (Hypotheses)

4. You wish to test the hypothesis that a beetle’s elytra protect the hind wings from damage.
So, you remove the elytra from 50 beetles, leave the elytra intact in 50 beetles, and release all 100 beetles into a large cage with thorny plants and examine the hind wings after 3 days.
A) If the hypothesis is correct, what result(s) would you expect?
B)  What results would be inconsistent with, or refute, the hypothesis?
