Q

Two compound eyes are separated.

A

Dichoptic

21
Q

Top of the head.

A

Holoptic

22
Q

The mandibles cut off and grind solid food, the maxillae and labium push it into the esophagus.

A

Mandibulate

23
Q

The mandibles are produced in sharp blades, and the maxillae into long probing style.

A

Cutting-Sponging Type

24
Q

The mandibles and maxillae are non-functional and the remaining parts form a proboscis with a sponge-like apex called LABELLA.

A

Sponging Type

25
Q

The mandibles and labrum are chewing type and are used to grasping prey, molding wax or nest material.

A

Chewing-lapping Type

26
Q

The mouthparts of this group are modified to pierce tissuesand suck juices from them.

A

Piercing Sucking Type

27
Q

The food either nectar or liquid food already are sucked up by means of long proboscis composed only of a united galea of each maxillae.

A

Siphoning Type

28
Q

Has a cone-shaped beak formed from clypeus labrum, parts of maxillae and labium.

A

Rasping-Sucking Type

29
Q

Epicuticle
Exocuticle
Endocuticle

34
Q

Separates the body wall with the internal organ.

A

Condition wherein the mouthparts are at the right angle to the body axis.

A

Hypognathous Head

41
Q

Condition wherein the mouthparts are projecting backwards between the legs.

A

Opisthognathous Head

42
