"Interestingly, the webs [decorated with crosses] were a little more sophisticated than we first thought," (researcher Dieter) Hochuli said.
"The spiders seem to be exploiting the sensitivity of some prey to UV light in particular. When we filtered different components of the visual spectrum from webs … we dramatically altered prey-capture rates," he said.
