Sorry for sharing unclear photo. In this hospital, my father’s room is at 3rd floor. One morning, when I saw the view outside from the window, I noticed this little guy on the window balcony outside. Aww, this little guy can fly this high!
I browse a while to search more information about this. Most insects can fly as long as they are in the air about fifty degrees Fahrenheit or warmer. If the air temperature at ground level is about seventy degrees, insects have about thirty-six hundred feet before they hit the ceiling and it’s too cold. On ninety-degree days, that limit is at about six thousand feet. If they achieve a height where it’s too chilly for them to fly, they just fold their wings in and go down until they reach a more comfy cruising elevation.
