1. Insect

2. Insect Body Parts  ab - abdomen  an - antenna  cpe – compound eye  cr – circus  epm – epimeron  eps – episternum  hd – head  la – labium  md – mandible  msn – mesonotum  mst – mesothorax  mtn – metanotum  mtt – metathorax  oc – ocellus  ov – ovipositor  prn – pronotum  prt – prothorax  ps – pleural suture  sp – spiracles  st – sternum  tg 1-10 – terga  th – thorax

3. Head  The head is the hardened (sclerotized) anterior region of the body that bears the eyes, antennae, and mouthparts

4. Mouth parts  Maxillae and mandibles are called Stylets  Labium- houses the feed channel and salivary tubes  Stylets- Pierce the tissues and contain section tubes  Labrum- Acts like a scabbard  Proboscis (tongue) uncoils by an increase in blood pressure.

5. Two General Types of Mouthparts chewing and piercing-sucking (opened)  an – antenna  cl – clypteus  cpe – compound eye  fr – frons  la – labium  lap – labial palpus  lb – labrum  md – mandible  mx – maxilla  mxp – maxillary palpus  oc – ocellus

6. Types of Antennae  A – setaceous  B – filiform  C – moniliform  D – elbowed  E – clavate  F – capitate  G – lamellate  H – ringed  I – aristate  J – serrate  K – pectinate  L – bipectinate  M – plumose

7. Types of Antennae  Setaceous

8. Filiform  - Thread like  -Uniform segs.  - Grasshopper  -Beetles

9. Moniliform  -Bead-Like  -Globular or Rounded  -Usually Uniform  - Common in Beetles & Termites

10. Elbowed  Wasps, Ants, Bees, Beetles

11. Capitate

13. Lamellate  -Leaf like, laminated  -Beatles  -June  -Carrion  -Scarab

14. Ringed

15. Aristate  Flies

16. Serrate  - Saw like  - Uniform segs.  - Coleoptera only

17. Pectinate - Comb. like - Certain moths and beetles

18. Bipectinate  Second set

19. Plumose  - Feather- like  - Flies and Moths

20. Salivary Juices  1. Softens cell wall  2. Anesthetizes  3. May Pre-digest  4. Anti Coagulants  5. Spread diseases

21. Thorax  - 2 nd major body part  - 3 segments (sometimes 4) If a 4 th segment is present it is called an alitrunk. Actually seems to be the 1 st Abdominal, but it’s the narrow waist in bees, ants, and wasps   a) Prothorax- Bears 1 st pair legs  b) Mesothorax- Bears 2 nd pair legs and 1 st pair wings  c) Metathorax- Bears 3 rd pair legs and 2 nd pair of wings  B and C = Ptera Thorax

22. General Wing  A – anal vein  aa – anal angle  am – anterior or costal margin  ap – apex  C – costa  cc – closed cell  Cu – cubitus  cu-a – cubito-anal crossvein  h – humeral crossvein  M – media  oc – open cell  pm – posterior margin  R – radius  r-m – radio-medial crossvein  Rs – radial sector  Sc – subcosta

23. Wings  Ptera- Winged  2 full sets of wings  Dipterous- 1 pair  Apterous- no wings  All immature insects are apterous  Wing veination for I.D.

24. Wing Form  - Elytra- Tough hard wing  - Hemelytra- ½ heathery ½ membranes

25. Tegminous  Forewing leathery  Orthortera  Membranous- clear delicate nerve like

26. General Insect Leg  cx – coax  fm – femur  pt – pretarsus (claws)  tb – tibia  tr – trochanter  ts – tarsus

27. Leg Shapes and specialization  1. Cursorial- wacking  Legs are basically all the same size and shape  2.Saltatorial  Saltar- To Jump  3.Raptorial  Rrapten- Claw like  Predators  4. Fessorial  Digging Legs

28. Parts of the leg

29. Leg Shapes and specialization  5.Natatorial  Pre-Natal  Swimming  Flat or Paddle like  -Thorax Houses Powerful locomotors muscles for  -Leg  -Wings  Contains part of the digestive tract, circulatory system and respiratory system.
