 Praying mantis
 SALTATORIAL
 Hind leg, jumping
 Enlarge femur

 POLLEN COLLECTING
 tibia adaptation (corbicula)
 Pollen basket
 KAKI BERPELEKAP (pg 26)
 Tarsus of fore leg
 With structure that can grasp
 To hold on female beetle during mating
INSECTS LARVAE
(refer practical book page 37)
 CAMPODEIFORM
 elongated, flattened, active
 Neuroptera
 CARABIFORM (pg 29)
 flattened, well-developed legs
 with no filaments on the end of the abdomen.
 Carabidae (beetle)
 SCARABAEIFORM
 sluggish, cylindrical, c-shaped
 well-developed head and thoracic legs
 Scarabaeidae (beetle)
 ELATERIFORM
 Wireworm
 elongate, cylindrical, with a hard exoskeleton
and tiny legs
 Elateridae (click beetle)
 ERUCIFORM
 Catterpillar-like
 Cylindrical, obvious head, short antennae
 Butterflies and moths
 PLATYFORM
 Very flattened larva
 Leg hidden or none
 Diptera (flies), Lepidoptera, Coleoptera (beetle)
 VERMIFORM
 Maggot (berengga)
 legless, head undevelop
 Diptera (flies)
INSECTS PUPAE (PG 38)
 EXARATE (EKSARAT)
 the appendages, legs etc., are free and capable of
movement
 Most orders except butterflies (lepidoptera) &
flies (Diptera)
 OBTECT (OBTEK)
 the legs and other appendages are closely
appressed to the rest of the body
 not capable of free movement
 butterflies
 COARCTATE (KOARKTAT)
 Enclosed within the last larval skin
 acts as a cocoon protects the pupa
 flies (Diptera, of the sub-order Cyclorrhapha.).
