Turn on your porch light after sunset, and you will be treated to an aerial display by dozens, if not hundreds, of bugs. Artificial lights attract moths, flies, crane flies, mayflies, beetles, and all sorts of other insects. I often find frogs and other insect predators hanging around my porch at night, taking advantage of the easy pickings.

Unfortunately for the insects, their attraction to artificial light is a cruel trick caused by our innovation moving faster than their evolution. Night flying insects evolved to navigate by the light of the moon. By keeping the moon's reflected light at a constant angle, the insects can maintain a steady flight path and a straight course.

Artificial lights interfere with an insect's ability to detect the moonlight. They appear brighter, and radiate their light in multiple directions. Once an insect flies close enough to a light bulb, it attempts to navigate by way of the artificial light, rather than the moon.

Since the light bulb radiates light on all sides, the insect simply cannot keep the light source at a constant angle, as it does with the moon. It attempts to navigate a straight path, but ends up caught in an endless spiral dance around the bulb.

Some scientists believe light pollution is leading to a decline in certain insects. Fireflies, for example, have difficulty identifying the flashes of other fireflies where artificial lights are present.

Can a fly fly into an empty jar and get out?

Certainly a normal empty jar would pose no problem for a bee to fly in and out. Like most insects they do tend to fly towards the light and upwards - but if that fails then they try other directions albeit on a fairly random basis.

How does an insect light attract and trap insects effectively?

An insect light attracts and traps insects effectively by emitting ultraviolet light that is attractive to insects, luring them towards the light source. Once the insects get close to the light, they are either electrocuted by the light or trapped in a sticky surface, preventing them from escaping. This method is successful in capturing a wide range of flying insects.


Why are June bugs attracted to light?

June bugs are attracted to light because they use the moon and stars to navigate at night. When they see artificial lights, they become disoriented and confused, leading them to fly towards the light source.


The locomotion of insects to the source of light is called?

The locomotion of insects towards a light source is called "positive phototaxis." This behavior is driven by the insects' attraction to light, which can aid in navigation and finding food or mates. Positive phototaxis is commonly observed in various species, particularly moths and other nocturnal insects.
