At night bugs fly to the light. how come they dont fly to the sun through the day?

Best Answer - Chosen by Asker

What they try to do is keep to a path that parallels the light. With the sun, there is no problem; distant objects seem to move so they will remain off to the side. With a nearby light, it will appear to move backward relative to the insect. That causes the insect to alter its path to keep the light off its side at an angle of 90 degrees. The result is that such an action will cause the insect to fly in an ever-decrasing spiral toward the light.

Answer 2

Actually, in the night,bugs use light sources such as stars as navigation points to find their way to their destination and back home at night. They do this because they have 360 degree vision unlike humans. Stars are at a distance of infinity which makes it possible to navigate by them. so is the sun. But since artificial light is a relatively new invention (only about 120 years old), bugs do not know what they are and navigate by them as well which sometimes leads them to go in a wide circular path which leads into the flame.

Answer 3

they use the moon for navigational cues. They get distracted by artificial light (as it's only been around for a century, it is not part of their adaptive history) and think they are flying toward the moon.

Interestingly other arthropods have adapted to artificial light, in that it is common to find spider webs around external light sources to catch the insects.

Answer 4

Because they are the nocturnal insects. When the light level gets too high they find somewhere to go to sleep.

Moths are attracted to blue and UV light wavelengths and are less sensitive to yellow light. They are adapted to navigate in dim moonlight and starlight. A bright light source at night confuses their navigation.

Answer 5

All insects are highly attracted by light. If all insects fly towards the sun as a direct sourse of light, no insect is going to inhibit earth. Give me three fingers down and I will put it this way ( the creator is the one who control every thing).

Answer 6

because they are asleep
IE they are nocturnal
