Phototaxis - The Charge Field and alignment with Photons
by Chromium6 Wed Sep 14, 2022 11:10 pm
Was looking at this recently. I was out at the pool swimming and had taken a some Harmine (radiates Ultra-violet in the bloodstream). Interestingly I was basically attack by three separate flying beetles. They went directly for my head and each one of them slammed it hard. Strangely, other folks in pool were not attacked by the beetles. Made me think my head could have been seen by them as a "Bug Light"...lol.

Phototaxis
Phototaxis is a kind of taxis, or locomotory movement, that occurs when a whole organism moves towards or away from a stimulus of light.[2] This is advantageous for phototrophic organisms as they can orient themselves most efficiently to receive light for photosynthesis. Phototaxis is called positive if the movement is in the direction of increasing light intensity and negative if the direction is opposite.[3]
Two types of positive phototaxis are observed in prokaryotes. The first is called scotophobotaxis (from the word "scotophobia"), which is observed only under a microscope. This occurs when a bacterium swims by chance out of the area illuminated by the microscope. Entering darkness signals the cell to reverse flagella rotation direction and reenter the light. The second type of phototaxis is true phototaxis, which is a directed movement up a gradient to an increasing amount of light. This is analogous to positive chemotaxis except that the attractant is light rather than a chemical.
Phototactic responses are observed in many organisms such as Serratia marcescens, Tetrahymena, and Euglena. Each organism has its own specific biological cause for a phototactic response, many of which are incidental and serve no end purpose.

Top: photophobic and scotophobic responses involving random tumbling or 180° motility reversals induced by sudden changes in the light environment experienced by the cells.
Middle: photokinesis involving changes in speed induced by changing light intensity. In patchy light environments, positive photokinesis results in accumulation in low light areas (and vice versa for negative photokinesis).
Bottom: true phototaxis results in movement towards or away from a light source, but is not a response to a light gradient. Direction of parallel illumination is indicated by the yellow arrows.

Insects
Moths are positively phototactic
Positive phototaxis can be found in many flying insects such as moths, grasshoppers, and flies. Drosophila melanogaster has been studied extensively for its innate positive phototactic response to light sources, using controlled experiments to help understand the connection between airborne locomotion toward a light source.[66] This innate response is common among insects that fly primarily during the night utilizing transverse orientation vis-à-vis the light of the moon for orientation.[67] Artificial lighting in cities and populated areas results in a more pronounced positive response compared to that with the distant light of the moon, resulting in the organism repeatedly responding to this new supernormal stimulus and innately flying toward it.
Evidence for the innate response of positive phototaxis in Drosophila melanogaster was carried out by altering the wings of several individual specimens, both physically (via removal) and genetically (via mutation). In both cases there was a noticeable lack of positive phototaxis, demonstrating that flying toward light sources is an innate response to the organisms' photoreceptors receiving a positive response.[66]
Negative phototaxis can be observed in larval drosophila melanogaster within the first three developmental instar stages, despite adult insects displaying positive phototaxis.[68] This behaviour is common among other species of insects which possess a flightless larval and adult stage in their life cycles, only switching to positive phototaxis when searching for pupation sites. Tenebrio molitor by comparison is one species which carries its negative phototaxis into adulthood.[68]
Relation to magnetic fields
Under experimental conditions, organisms that use positive phototaxis have also shown a correlation with light and magnetic fields. Under homogeneous light conditions with a shifting magnetic field, Drosophila melanogaster larvae reorient themselves toward predicted directions of greater or lesser light intensities as expected by a rotating magnetic field. In complete darkness, the larvae orient randomly without any notable preference.[68] This suggests the larvae can observe a visible pattern in combination with light.

Why are Bugs Attracted to Light?

There’s a good chance that you’ve heard the saying, “like a moth to a flame,” when someone finds something completely irresistible. For example, Susan was drawn to the sparkling pair of earrings like a moth to a flame, or Steve was drawn to the vintage Lamborghini like a moth to a flame. This saying, which Shakespeare made famous, clearly has roots in nature.
If you’ve ever sat on a patio or taken an evening stroll, you’ve probably noticed different bugs fluttering around floodlights and streetlamps. While it’s easy to simply say that bugs like light, the phenomenon is actually a bit more complex. In fact, scientists have studied this phenomenon for years and have developed a number of theories to explain why certain bugs are drawn to light. Furthermore, we can’t even say that all bugs are attracted to light. A few types of bugs try to steer clear of it entirely.
What Bugs are Attracted to Light?
Think back to all of the times you’ve been outside at night, turned on a light or two, and witnessed bugs fly directly to the source of light. More than likely, you’ve seen a fair share of moths and beetles make their way to that luminous glow. That’s because these insects have positive phototaxis.
Phototaxis is a type of innate behavioral response (in this case, a directional movement) that takes place when an organism moves towards or away from a light source. Insects and pests that are attracted to light, and move towards it, are considered positively phototactic. On the flip side, pests that move away from a light source are considered negatively phototactic.
While there are many different theories explaining why pests, such as moths, flies, beetles, and stink bugs, are attracted to light, one of the most popular theories has to do with navigation. Many scientists believe that insects are drawn to light because they use light as a guide. Before insects evolved and adapted to artificial light sources, they relied on the Sun, Moon, and stars in order to navigate. Many scientists believe that some bugs use transverse orientation for navigational purposes. Transverse orientation involves keeping a distant light source at a fixed angle in order to fly in a straight line. When you introduce man-made artificial light, insects start to confuse that light for natural light sources. This throws of their ability to keep light at a constant angle, which results in insects fluttering into or around artificial light sources.
In addition to navigation, many scientists believe that some bugs are attracted to light because it offers protection from predators and dangers that lurk at night. Meanwhile, another theory suggests that some insects confuse artificial light for flowers. While this may seem pretty bizarre, there are actually some flowers that reflect ultraviolet light. As a result some flying insects may mistake your outdoor lights for a food source.
Negative Phototaxis
Just as some bugs flock to the light, some try to avoid it. It’s pretty intuitive when you think about it. Recall a time when you’ve switched on a light and witnessed pests scurrying away to different hiding places. While you may have simply frightened these pests, there’s a good chance that they are negatively phototactic. Some creatures that are known for their negative phototaxis include cockroaches, earthworms, and a few different types of ants.
Cockroaches, in particular, have a major dislike for both artificial and natural light. As a result, it is very uncommon to see roaches out during the daytime or in bright, light-filled rooms. If you do happen to see roaches out during the day, it’s likely you have a problem on your hands. The roaches that come out during the day have been forced out because their home has become too populated and they are looking for food. In other words, you may have an infestation.
While scientists are still trying to figure out why bugs are attracted to light, there are some ways to limit the amount of bugs flocking to your home’s lighting. Your best bet is to check you lightbulbs. If you are using incandescent, CFL, or halogen bulbs, you are likely attracting bugs. If possible, try to replace any of these bulbs with warm LED bulbs.
If you are tired of pests disrupting your patio time or notice negative phototactic bugs, such as cockroaches, out and about during the day, call your local Aptive Environmental branch today.
