27
* wing with Modification of hindwing which helps in balancing and improve flight
* Example: Hindwing of Diptera (Housefly)
Haltere
28
* No metamorphosis happens
* Immature forms resemble the adults
* Immature Stage is called “Juvenile”
* Example: primitively wingless insects (Silverfish, Springtails)
Ametabolous
29
* Gradual metamorphosis happens
* Immature forms resemble the adults but immature forms has underdeveloped genitalia and has wing pads
* Occurs in non-aquatic form
* Immature and Adult forms are both destructive
* Immature Stage is called “Nymph”
* Example: Hemiptera, Orthoptera, Blattodea
Paurometabolous
30
* Incomplete metamorphosis happens
* Immature forms do not resemble the adults
* Immature forms have different habitat compared to its adults
* Immature Stage is called “Naiad”
* Example: Odonata
Hemimetabolous
31
* Complete metamorphosis happens
* Have four distinct life stages: Egg, Larva, Pupa, Adult
* Immature forms have the same habitat as to its adults
* Only immature forms are
destructive
* Immature Stage is called “Larva”
* Example: Lepidoptera
Holometabolous
32
* Generally looks like caterpillars
* Cylindrical with well-developed head capsule and a short antennae
* Have both thoracic (true legs) and
abdominal legs (pseudolegs)
* Example: Lepidoptera
Eruciform
33
* Generally looks like grubs
* Curved or C-shaped with well developed head capsule
* Have thoracic (true legs) but no abdominal legs (pseudolegs); Slow and sluggish
* Example: Coleoptera (Scarabaeoidea)
Scarabeiform
34
* Active and Predatory
* Slightly flattened, elongated bodies
* Have well-developed legs, antennae, and cerci
* Example: Coleoptera, Trichoptera,
Neuroptera
Campodeiform
35
* Generally looks like worms, but with sclerotized (hardened) bodies
* Have short legs and reduced body bristles
* Have both thoracic (true legs) and abdominal legs (pseudolegs)
* Example: Coleoptera (Elateridae)
Elateriform
36
* Generally looks like maggots
* Elongated bodies that may or may not have well-developed
headcapsules
* Example: Diptera
Vermiform
37
* Appendages are fused to the body wall as exoskeleton hardens.
* Enclosed within a cocoon
* Example: Lepidoptera, Few Hymenoptera, Diptera (midges, craneflies)
Obtect
38
* Opposite of obtect pupae; appendages are free and are able to move
* Lacks cocoon, looks like a mummified adult
* Example: All insects undergoing complete metamorphosis
Exarate
39
* Have articulated mandibles (used to chew pupal cell)
* Tend to be active, exarate with free appendages
* Example: Neuroptera (Lacewing)
Decticous
40
* Lack functional mandibles; are attached to the head rendering them immobile
* May be either be obtect or exarate * Example: Adecticous Obtect (Diptera, Lepidoptera, Coleoptera, Hymenoptera); Adecticous Exarate (Coleoptera, Hymenoptera)
Adecticous
41
* Covered with a membrane called “puparium”, a hardened cuticle of the final instar level.
* Example: Diptera (Brachycera
Coarctate
