Butterflies flap their wings for 5 to 6 seconds per second, flies.
100 to 120 flapps per second, sparrows flapp 15 to 20 times per second, bees flapp 300 to 350 times per second, mosquitoes flapp 450 to 500 times per second The activity of flies is greatly affected by temperature. It can only crawl at 4 7 o'clock, fly at 10 15 o'clock, feed, mate, and lay eggs at 20 o'clock or more, it is especially active at 30 35 o'clock, 35 40 ceases to be active due to overheating, and it dies at 45 47 o'clock. Flies are good at flying.
It can fly at a speed of 6 8 kilometers per hour and a maximum of 8 18 kilometers per day and night. However, they usually move within a radius of 100 200 meters from the breeding ground, and most of them do not exceed 1 2 kilometers. Flight characteristics at takeoff:
During the initiation phase of takeoff, flies always bounce through the "kicking" action of the midfoot and hindfoot, leaving the ground and winging in seconds. The fly's flight path is often less than 40 degrees to the ground, and only by chance does it occur at a near-vertical take-off inclination, but it turns to an inclination angle after 10 mm above the ground.

Insect wings evolved from ancient wings. The muscles that activate its functions are within the thoracic cage, and the muscles are not attached to the wings, which is unique to the insect "flying machine". Birds and bats, on the other hand, have muscles on their wings, so they must be supported by a heavy skeleton.
For example, the wings of dragonflies are thin and light, weighing only 0 005 grams, but they can vibrate more than 50 times per second and fly at speeds of up to 40 meters per second. In addition, some mosquitoes can flap their wings 1,000 times a second, flies 147,200 times, bees 180,203 times. The hummingbird, the highest bird record holder, does not flap its wings more than 50 times per second.
There is a kind of fly that lives near the water, and it can flap its wings more than a thousand times a second.
