  12. tentorium
    invagination of the body wall in the insect head
  13. spiracles
    openings of the respiratory system
  14. pleural sutures

    • sternites
    • tergites
  16. thoratic segments w/ and w/o wings
    w/o wings plueron isn't sclerotized
  17. insect leg parts

    • tibia
    • tarsus
    • pretarsus
  18. raptoral legs
    enlargerd coxa
  19. clasping
    • leg with femer and tibia formed into pincer-like structure
    • for holding hair
  20. Wings
    • usally entirely membranous with upper and lower membranes
    • veins from tracheal tubes
    • venation is specific
    • attached by membranous hinge
    • small sclerities assist in articulation
  21. wing coupling mechanisms
    • frenulum- large spine- in moths
    • jugum- lobe attaches to rib- rare moths
    • Hamulus- like velcro - butterflys
  22. Orthoptera
    • straight wings
    • grasshoppers, crickets, cockroaches
  23. isoptera
    • equal sized wings

  26. lepidoptera
    • scaly-wings
    • moths, butterflys, skippers
  27. diptera
    • only one pair of wings
    • house flys, mosquitoes
  28. direct flight musles
    • muscles attach directly to wings
    • only in dragon fly
    • damsel fly
    • may fly
  29. Indirect flight muscles
    • contract longitudinal muscles = wings down
    • contrat dorsal ventral = depress notum and wings up
  30. why not three wings?
    because not enough from for muscles in pro-thorax region
  31. median intromittent organ
    • copulartory organ
    • male repro
    • the aedegus
  32. clasping organs
    • parameres

    • 1st valvifer from 8th body segment
    • 3rd and 2nd on 9th body segment
    • used as egg guides
