Summary
[edit]DescriptionA GOLDEN SPIDER USING ITS VERY OWN RAINBOW TO CATCH PREY.jpg |
English: An unknown light phenomenon in nature created by a spider and used to attract small flying insects to fly into the spider web it weaves. The golden spider inhabits the northern parts of Queensland, Australia, where its closest relative, the Northern St Andrew's Cross Spider - Argiope picta - also occurs. But this particular spider has not yet been given a scientific name. Like its closest relative, the new spider uses light to attract small flying insects. The spiders live side by side in the same environment but with different methods of capture. The Northern St Andrew's Cross Spider uses light reflected from woven structures interlaced in the spider's web to attract flying insects, with the difference that the new spider has these interwoven structures behind the web instead - grouped in long ribbons. You can even count the breadths in the silk - 7 lines - in the picture.
In this very moment, the golden spider has caught a small flying insect in the web, while at the same time you can see the spectrum that leads in a path straight through the center of the spider's orb web and towards a point behind the web so that if the prey following the path, it ends up where the catching threads are densest in the center of the web. And it is that kind of a small flying insect, that the spider just has caught. One of nature's many unsolved mysteries - a virtual spectrum! Just like in the rainbow. |
