External Structure of Insects, Functions & Locomotion • • • • Insect surface: exoskeleton & epidermis Head: Mouthparts, Antennae, Eyes Thorax:Thoracic segments, Wings, Legs Abdomen: Segments,Ovipositor,Cerci,Style REMEMBER EXOSKELETON? FUNCTION?? Function of Exoskeleton • • • • Body support Protection Water conservation Location of muscle attachment - allows movement • Colouration & Camouflage THE INSECT SURFACE (Exoskeleton) - glycoprotein Dermal gland: produce pheromone, repellant Exoskeletal Parts • • • • Tergite/Tergum (Dorsal,Abdomen) Notum (Dorsal, Thorax) Pleurum (Lateral) Sternite/Sternum HEAD MOUTH PARTS • • • • • Clypeus Labrum (“upper lip”) Labium (‘lower lip’) Mandibles (‘jaw-like) Maxillae ADAPTATIONS OF THE MOUTHPARTS • MANDIBULATE – • HAUSTELLATE – – A) Stylet – – B) Proboscis – – C) Sponging – THE EYES • 2 Types: a) Compound eye b) Ocelli (sing. Ocellus) THE ANTENNA • For touch and smell ( some case hearing) THORAX • • • • Pro,meso,meta Notum & Pleuron Wings Legs THORAX HALTERE -balancing- PRO MESO META DIPTERA- TRUE FLIES NOTUM (DORSAL) PLEURON (LATERAL) LEGS TYPES OF INSECT’S LEGS • CURSORIAL • FOSSORIAL • RAPTORIAL • SALTATORIAL • NATATORIAL • POLLEN COLLECTING WINGS • • • • • • • ELYTRON TEGMINA HEMIELITRON MEMBRANOUS HALTERE SCALE-LIKE FRINGED Fringed-like Scale-like wing (butterflies & moths) INSECTS LARVAE • CAMPODEIFORM • • • • CARABIFORM (pg 29) flattened, well-developed legs Carabidae (beetle) short legs, short cerci and a flattened body. • SCARABAEIFORM • ELATERIFORM • Wireworm • ERUCIFORM – PLATYFORM • VERMIFORM INSECTS PUPAE • EXARATE (EKSARAT) • OBTECT (OBTEK) • COARCTATE (KOARKTAT) •
