Arthropods - Centipedes, Millipedes, and Insects

Flashcards covering the characteristics of Chilopoda (Centipedes), Diplopoda (Millipedes), and Insecta.

Chilopoda (Centipedes) Habitat

Moist terrestrial environments

Chilopoda (Centipedes) Key Structures

Flattened body, 1 pair of legs per segment, venom claw

Chilopoda (Centipedes) Reproduction

Internal; lay eggs

Chilopoda (Centipedes) Life Cycle

Egg → juvenile → adult

Chilopoda (Centipedes) Ecology

Carnivorous predators

Chilopoda (Centipedes) Appearance

Long, fast-moving, many segments

Diplopoda (Millipedes) Habitat

Damp forests, soil

Diplopoda (Millipedes) Key Structures

Cylindrical body, 2 pairs of legs per segment, exoskeleton

Diplopoda (Millipedes) Reproduction

Internal fertilization; lays eggs in soil

Diplopoda (Millipedes) Life Cycle

Egg → molts → adult

Diplopoda (Millipedes) Ecology

Decomposers, feed on dead plants

Diplopoda (Millipedes) Appearance

Slow, many segments, curled when threatened

Insecta Habitat

Terrestrial, some freshwater

Insecta Key Structures

3 body parts (head, thorax, abdomen), 6 legs, antennae, compound eyes, wings (in most)

Insecta Mouth

Varies; chewing (grasshopper), sucking (butterfly), lapping (bee)

Insecta Reproduction

Sexual; internal fertilization

Insecta Life Cycle

Complete metamorphosis (egg → larva → pupa → adult) OR incomplete (egg → nymph → adult)

Bees

Complex social roles (queen, worker, drone); pollinators

Grasshoppers

Incomplete metamorphosis; powerful jumping legs

Insecta Ecology

Pollinators, decomposers, prey/predators

Insecta Diversity

Most diverse class on Earth

Insecta Homeostasis

Tracheal system for breathing

Insecta Unity

Segmented body, jointed limbs, exoskeleton
