Answer 1

Answer:

hey mate here is your answer

Larger insects such as cockroaches, beetles, locusts and grasshoppers require more pumping action. This helps them when they are active or when they are undergoing stress due to heat. Larger insects open and close separate spiracles with their abdominal muscles to move air throughout their bodies.
