Study Notes
Metamorphosis
- Definition: A biological process in which an animal undergoes a series of physical transformations from birth to adulthood
- In butterflies, metamorphosis involves four stages: egg, larva, pupa, and adult
- Characterized by dramatic changes in form and structure
Adult
- Also known as imago
- Final stage of metamorphosis
- Characteristics:
- Wings: fully developed, colorful, and delicate
- Body: slender, elongated, and hairy
- Mouthparts: modified for sipping nectar from flowers
- Reproductive organs: fully developed for mating and egg-laying
- Lifespan: varies by species, typically 1-4 weeks
Pupa (Chrysalis)
- Stage of metamorphosis where transformation from larva to adult occurs
- Characteristics:
- Non-mobile, resting stage
- Body: encased in a protective casing (chrysalis)
- Tissues and organs are reorganized to form adult structures
- Duration: varies by species, typically 2-4 weeks
Egg
- First stage of metamorphosis
- Characteristics:
- Laid on leaves or stems by female butterfly
- Small, oval, and usually yellow or white
- Fertilized by male butterfly's sperm
- Incubation period: varies by species, typically 3-4 days
Larva (Caterpillar)
- Second stage of metamorphosis
- Characteristics:
- Eats constantly to grow and store energy
- Body: segmented, worm-like, and often hairy
- Legs: several pairs of prolegs and thoracic legs
- Instars: molts several times as it grows, typically 5-6 times
- Duration: varies by species, typically 1-4 weeks
