BS Zoology Semester Exam MCQs

Wing veins strengthen insect wings and also contain tracheae, nerves, and hemolymph. Venation patterns are important in insect identification.

The abdomen is the posterior body region of insects. It houses many internal organs, including gut, reproductive organs, Malpighian tubules, tracheae, and the dorsal vessel.

Insect flight depends on wing motion, air flow, and pressure differences that create lift. Wing shape, beat frequency, and angle of attack influence flight performance.

Jumping insects such as grasshoppers have enlarged hind femora with strong muscles. These legs store and release force for sudden jumps.

Ocelli are simple light-sensitive organs. They generally help insects detect light intensity and maintain orientation rather than forming detailed images.
