Why Do Spiders Need Sunlight?
WouterMany people ask whether spiders need sunlight. While most species do not, there are some species that are very attracted to light. This is due to the spider’s need to see.
The quality of the silk produced by a spider is enhanced by ultraviolet rays. This is important to spiders since it increases the strength of their webs. The better the silk, the lower the risk of being eaten. Likewise, it improves the defense mechanisms of the spider, which is important for the protection of the spider from predators.
Another reason why some spiders are attracted to light is that they need light to hunt. This is particularly true for nocturnal spiders, which are known to have poorer eyesight than the other species.
Aside from catching prey, nocturnal spiders also use light as a signal to navigate. This helps them to avoid too much light. In addition, it provides them with a clearer image of swarms of insects.
In the case of urban web-spinning spiders, they could lose their photophobia. In cities, streetlights and other artificial lights are used. In addition, the presence of clutter can provide hiding places for spiders.
Some people have found that a nocturnal spider will take up residence near a light source, such as a computer monitor or phone. It is also important to note that nocturnal spiders avoid light in the evenings, while diurnal spiders are attracted to light during the day.
In the end, it is up to you to decide whether you want to keep a nocturnal spider in your home or not. If you aren’t worried about the animal, you can simply leave the light on. However, if you’re concerned about the presence of spiders, you may want to try to eliminate the sources of light around your home.
