Spiders kidnapping the brightness to create the incandescent death traps

Wreaths Radiate To attract his colleagues. However, as new research shows, it has learned a certain type of spider to take advantage of this bright natural phenomenon.

in Animal Environment Magazine Paper published on August 27, environmental scientists state that the Seintweb spider (Psechrus ClavisIt appears to exploit the brightness to attract more prey. Observation analysis and laboratory experiments revealed that using the light of the brightness as a taste, night predators improved the success of hunting. This is it The second time that researchers have noticed such behavior in spidersAlthough the new paper describes completely different types of spider.

“This study highlights the new ways on the ways that predators and night waiting animals can rise to the challenges of attracting prey and providing a unique perspective about the complexity of the predator predators,” said I-MIN TSO, one of the senior authors of the study at Taiwan University in Taiwan. Release.

A tendency to bright down

What the researchers have alerted to this strange behavior is the tendency of spiders to consume most of the larvae – such as mites – in their networks, but not the wrestles. When the incandescent creatures turned into a metropolitan network, the spider simply left for them for about an hour, even sometimes they crawl to see if the wreaths are alive and glowing.

This looked strange for researchers. They knew that this was not because the spiders were not in the wreaths – on the contrary. It is clear that the researchers were unable to ask the spiders if they simply appreciate the beautiful bridges. So instead, arrange an experiment to test if the behavior of spiders could be linked to evolutionary benefits.

For the experiment, the team prepared the LED lights, which is very similar to the glow of the wrestling, which brought it down on the seintweb spiders. These LED networks are three times the amount of prey compared to the controls without any lights.

The most surprising, when the researchers restricted the prey to the real lifesters, the LED lights attracted ten times the lights of which – most of them are males. This indicates that the wrestles were mistaken in the artificial glow of its potential colleagues.

“Dealing with prey in different ways indicates that the spider can use a kind of signals to distinguish between the prey types they pick up and determine an appropriate response,” I explained TSO. ))

However, the researchers admitted that their experience used an artificial repetition of the glow of the fireplace. Ideally, the field experience will use real lifesters, although this will be “very difficult to practice.”

Not to mention immoral. Many types of wires are listed as threatening.

It is tempting that spiders simply appreciate the soft glow that is added to their networks. But since the evolutionary behavior tends to go, the hypothesis of researchers seems valid. So so that we can discover the spider’s connection, we will just have to assume the latter.
