INSECTS OFTEN GATHER NEAR LIGHTS, WHO WOULD HAVE THOUGHT THESE ARE THE REASONS INSECTS OFTEN GATHERING NEAR LIGHTS AT NIGHT
Insects often gather near lights at night. Let us try to pay attention to the insects around you at night. Usually, the insects will congregate near the light. Sometimes, this situation can be annoying.
However, do you know friends? It turns out that there are several reasons why insects often congregate near lights. Letak us find it out!
Phototaxis Phenomenon
The phenomenon of phototaxis describes how organisms respond to light by movement.
Insects that move toward light, such as moths, are said to be phototactic positive.
On the other side, there are also insects that avoid light such as cockroaches that move away from light. These insects are called negative phototactic.
Insects Follow Natural Light
One theory about insects that are phototactic positive is that they are attracted to light because light acts like a guide.
There are insects that follow natural light, namely sunlight or moonlight at a certain angle.
However, when looking at artificial light such as lamplight, insects can also be confused.
It is possible that the insects thought the light from the lamp was the light of the Sun or the Moon.
So, instead of following a certain angle from the light of the Sun or Moon, insects follow the light of the lamp.
As a result, they circle around the light which can make them dizzy and stressed.
Light for Guides
Another theory expressed by researchers is the possibility of artificial light in lamps being a clear guide for insects.
So, instead of flying in a dark area, the insects go straight to the light because the environment around the light is seen more clearly.
Thinking of Light Like a Flower
Another opinion of scientists is the possibility of insects mistakenly interpreting the artificial light from the lamp as a flower.
Some types of flowers do reflect ultraviolet light, friends.
Well, artificial light also emits a little ultraviolet light. Some insects may mistake it for flowers that are their food source.
