Insects fly by air aerodynamics lift,thrust,drag,gravity! Sheesh use your brains!

To fly.
Insects have specialized wings that provide lift and thrust for flight. Their small size and lightweight exoskeleton also contribute to their ability to fly efficiently. Additionally, insects have well-developed flight muscles and a unique respiratory system that allows them to meet the high energy demands of flying.
Evolution of Flight- chronologically, the ability to fly evolved in this order:1. insects, 2. pterosaurs, 3. birds, 4.bats.- the last three organisms are vertebrates.
The reciprocal evolution of flowers and insect mouth parts has occurred over millions of years. The flowers change to make their nectar inaccessible to insects while insects change to be able to attain the nectar.
Evolution.
Mainly flying insects, which are caught in flight.
Insects became resistant because the insecticides were used on the continuously. Most insects will die at first, but there will be some that have the right genetics to resist that insecticide. When that happens the insect will the favorable gene reproduces and creates more insects that are resistant. Humans promoted this evolution by using the same insecticide on the insects.
To facilitate flight .
Contract and relax to enable movements and flight.
