Presentation Transcript

  1. TYPES OF INSECT’S LEGS • CURSORIAL • Wakling, running • Ground beetles, cockroach

  2. FOSSORIAL • Front leg, digging soil • Mole cricket

  3. RAPTATORIAL • Fore leg, adapted for catching prey • Praying mantis

  4. SALTATORIAL • Hind leg, jumping • Enlarge femur • grasshoppers

  5. NATATORIAL • For swimmng • With hairs • Water beetles

  6. POLLEN COLLECTING • tibia adaptation (corbicula) • Pollen basket

  7. KAKI BERPELEKAP (pg 26) • Tarsus of fore leg • With structure that can grasp • To hold on female beetle during mating

  8. INSECTS LARVAE(refer practical book page 37) • CAMPODEIFORM • elongated, flattened, active • Neuroptera

  9. CARABIFORM (pg 29) • flattened, well-developed legs • with no filaments on the end of the abdomen. • Carabidae (beetle)

  10. SCARABAEIFORM • sluggish, cylindrical, c-shaped • well-developed head and thoracic legs • Scarabaeidae (beetle)

  11. ELATERIFORM • Wireworm • elongate, cylindrical, with a hard exoskeleton and tiny legs • Elateridae (click beetle)

  12. ERUCIFORM • Catterpillar-like • Cylindrical, obvious head, short antennae • Butterflies and moths

  13. PLATYFORM • Very flattened larva • Leg hidden or none • Diptera (flies), Lepidoptera, Coleoptera (beetle)

  14. VERMIFORM • Maggot (berengga) • legless, head undevelop • Diptera (flies)

  15. INSECTS PUPAE (PG 38) • EXARATE (EKSARAT) • the appendages, legs etc., are free and capable of movement • Most orders except butterflies (lepidoptera) & flies (Diptera)

  16. OBTECT (OBTEK) • the legs and other appendages are closely appressed to the rest of the body • not capable of free movement • butterflies

  17. COARCTATE (KOARKTAT) • Enclosed within the last larval skin • acts as a cocoon protects the pupa • flies (Diptera, of the sub-order Cyclorrhapha.).
