  1. Phylum Arthropoda Subphylum 4 Uniramia ‘DIC’ or ‘CID’ ClassChilopoda ClassDiplopoda ClassInsecta Which one has most legs per segment?

  2. Subphylum 4 Uniramia Rounded head with no obvious jaws as it is a deposit feeder ClassDiplopoda 2 pairs of legs/segment ClassChilopoda 1pair of legs/segment Vicious jaws of a carnivorous predator

  3. Suphylum 4UniramiaClass Insecta The “bugs!” Ah! The smell of mothballs!

  4. Metamorphosisis the change from a LARVAL form to…… an ADULTform …which grows by MOLTING ..but does NOT REPRODUCE ..which does not grow (MOLT) ..but does REPRODUCE =

  5. Their wings have G T G HOLOMETABOLISM T T U T

  6. Holometabolism Holometabola = Endopterygota 4 ORDERS Egg -> larvae -> pupa -> adult Aquatic nymph

  7. Holometabolism • 4 ORDERS • Wings on the INSIDEin the larva and must undergo acomplete metamorphosisto bring them out in the adult. This is a VERY dramatic change

  8. DivisionEndopterygota: HolometabolousLife Cycle4 ORDERS: HLCD OrderHymenoptera Bees, ants, wasps OrderLepidoptera Butterflies, moths Bugs for decorating a nursery or a children’s picture book. Order Coleoptera Beetles. Look for “T” formed by ELYTRA Order Diptera True flies Look for HALTERES

  9. Hemimetabolism 5 ORDERS - Wings on the OUTSIDE in the larva already. Only need an incomplete/partial metamorphosis = (using half of the effort)to bring the insect to the mature adult stage.

  10. W HEMIMETABOLISM NL U G R T S E A D Y

  11. Hemimetabolism Incomplete metamorphosis Wings on the outside Hemimetabola = Exopterygota 5 ORDERS egg-> nymph(mini adult)-> adult (Naiad if aquatic)

  12. DivisionExopterygota: HemimetabolousLife Cycle5 ORDERS: Odonata Hemiptera Order Order Bug allies (assassin bugs, bedbugs) Dragonflies, damselflies Look for “X” on back formed by wings crossing over each other O H H I O Homoptera Order True bugs (cicadas, aphids) Order Isoptera Look for “home” formed by wings over back of insect Termites Orthoptera Order Head-on Crickets, grasshoppers, roaches

  14. SubphylumUniramiaClass Insecta Hymenoptera Lepidoptera Hemiptera Orthoptera Coleoptera

  15. Don’t forget that the fore- and hind gut portions are from ectodermally derived tissues! Inside a Grasshopper… Remember the baseball and glove?

  16. Phylum Arthropoda, Subphylum Uniramia, Class Insecta, Order Orthoptera Crop - storage Proventriculus – grinding = mechanical digestion Gastric Caecum - chemical digestion Female has ovarioles (looks like rice grains!) Malpighian Tubules - excretion Respiratory system = Tracheal system (has spiracles etc.)
