Appearance and Physical Characteristics
- Soft-bodied insects with three main body parts.
- Two pairs of large wings covered with tiny coloured scales.
- Long tube-like mouthpart called a proboscis for sucking nectar.
- Six jointed legs and two antennae.
- Butterflies usually have club-shaped antennae, while moths often have feathery or thread-like antennae.
Lepidoptera Habitat and Distribution
Lepidoptera habitat ranges from tropical rainforests to deserts and grasslands. They are highly adaptable insects.
- Common in gardens, meadows, forests, and farms.
- Some species live in mountains and cold regions.
- Caterpillars usually stay on specific host plants.
- Many butterflies prefer warm and sunny environments.
Diet and Feeding Habits
Adult Stage
- Mainly feed on flower nectar.
- Use their proboscis like a straw to drink liquids.
- Some moths feed on fruits or tree sap.
Caterpillar Stage
- Mostly herbivores.
- Feed on leaves, stems, and sometimes crops.
- Grow quickly and eat large amounts of food.
Behaviour and Lifestyle
- Butterflies are mostly active during the day (diurnal).
- Many moths are nocturnal (active at night).
- Some species migrate long distances.
- Bright wing colours can warn predators or help in camouflage.
- They use chemical signals called pheromones to communicate.
Lepidoptera Life Cycle
- Egg: Laid on leaves or host plants.
- Larva (Caterpillar): Eats and grows rapidly.
- Pupa (Chrysalis or Cocoon): Body transforms inside a protective covering.
- Adult: Emerges with wings ready to fly and reproduce.
