1. Modification of legs and antenna1

2. 2

3. Antenna One Pair on head Jointed Sensory (smell) Called “feelers”
Filiform most common shape (segments = size)
May be modified
FILIFORM 3

4. Plumose antenna
These type of antenna have horizontal brushes on root antenna
They are found in moth and mosquito

5. Setaceous antenna
These are simplest type of antenna having bristle shape
They are found in dragon fly

6. Aristate antenna
Pouch like with a lateral bristle.
Example-house fly

7. Capitate antenna
Abruptly clubbed at the end.
Example-butterfly

8. Clavate antenna
Gradually clubbed at the end
Example-carion beetles

9. Filliform antenna
They have thread like shape
Example-ground beetles

10. Geniculate antenna They are hinged or bent like an elbow
Example-bees and ants

11. Monoliform antenna
They are bead like in shape
Example-termites

12. Pectinate antenna Comb like shape
Example-glow worm and fire coloured beetles

13. Serrate antenna
They are saw toothed shape
Example-click beetles

14. There are ALWAYS SIX legs, and they are attached to the THORAX
Leg modification
There are ALWAYS SIX legs, and they are attached to the THORAX 14

15. cursrial(running)-These are the legs of the tiger beetle, a voracious predator. It chases down its prey, much like the tiger after which it is named. The long reach of the leg allows it to move so quickly and results from the long femur and tibia

16. Raptorial leg- The giant water bug is ferocious predator that traps its prey using the large raptorial prothoracic legs. The femur and tibia form a pincer-like grip. As a hemipteran, this insect has piercing mouth parts. Eg.
Belostomatidae,mantis

17. Natatorial(swimming legs)- the water insects have these type of legs
Natatorial(swimming legs)- the water insects have these type of legs. Tibia tarsus part have hairs which help is swimming.eg water beetles, Belostomatidae

18. Fossorial(digging legs)-the metathoracic legs of some insects are modified for digging tunnel.eg –mole cricket

19. Grasping legs- some insects have metathoraic legs modification for holding an object.eg-hair louse have a pit in its legs to hold the hair

20. Saltatorial(jumping)-
Grasshoppers and crickets have the classic example of the sartorial jumping leg. When the muscles in the femur contract, the joint between the femur and tibia straightens, and the hopper is launched into the air

21. Honey bee legs-
The metathoracic leg of the honey bee is modified for gathering pollen. The first tarsal segment is very large, and students often confuse it with the tibia. The shape of the tibia and setal hair form a pollen basket. Pollen is packed into the basket by the spine of cuticle on the first tarsomere and is indicated by the pointer
