Study Notes
Insect Anatomy
-
Body structure: Insects have a three-part body consisting of:
- Head
- Thorax
- Abdomen
- Exoskeleton: Made of chitin, a hard, flexible material that provides protection and support
- Sensory organs: Insects have compound eyes, simple eyes, and antennae for sensing their environment
- Wings: Most insects have two pairs of wings (forewings and hindwings) that are attached to the thorax
- Legs: Insects have three pairs of legs, which are used for movement, sensing, and feeding
Insect Life Cycle
-
Stages: Insects undergo a process called incomplete metamorphosis, which includes:
- Egg: Insects lay eggs, which hatch into...
- Nymph: A juvenile stage that resembles a small adult, but lacks reproductive organs
- Adult: The final stage, where insects are fully developed and can reproduce
- Molting: Insects shed their exoskeleton as they grow and develop, a process called molting
- Duration: The length of the life cycle varies depending on the species and environmental factors
Insect Habitat
-
Diverse environments: Insects can be found in almost every habitat on Earth, including:
- Terrestrial (land)
- Freshwater (rivers, lakes, ponds)
- Marine (oceans)
- Aerial (air)
-
Ecological niches: Insects occupy various niches, such as:
- Herbivores (plant-eaters)
- Carnivores (meat-eaters)
- Omnivores (both plant- and meat-eaters)
- Decomposers (break down organic matter)
-
Adaptations: Insects have evolved unique adaptations to survive in their environments, such as:
- Camouflage
- Migration
- Hibernation
- Burrowing

Insect Life Cycle
- Insects undergo incomplete metamorphosis, which includes egg, nymph, and adult stages
- Eggs hatch into nymphs, which resemble small adults but lack reproductive organs
- Nymphs undergo molting as they grow and develop, eventually becoming adult insects
- Adult insects are fully developed and can reproduce
- The duration of the life cycle varies depending on the species and environmental factors
Insect Habitat
- Insects can be found in almost every habitat on Earth, including terrestrial, freshwater, marine, and aerial environments
- Insects occupy various ecological niches, including herbivores, carnivores, omnivores, and decomposers
- Insects have evolved unique adaptations to survive in their environments, such as camouflage, migration, hibernation, and burrowing
