Just to be clear, there's no evidence of the trap failing to close on a pollinator insect in its jaws. It's just that the pollinators don't seem to go near the traps.
Still interesting, just not quite as amazing as the title might imply. I was picturing the symbiosis of sharks and the creatures that clean their teeth before reading, but it's not quite like that.
While the article title is a true statement, the ambiguities of the language may create a false impression of Venus flytraps "knowing" who pollinates them and not eating those species. This is not how natural selection works. Some mutations of Venus flytraps produced a variation in placement and color of the traps that allowed some species to pollinate them. If there ever were (or will be) a mutation of a Venus flytrap that catches and eats everything, there will be no one to pollinate these and they will die out as a result.
We should not leave Lysenkoism a chance, even if it is in the subtleties of language.
If a bee is one of the pollinators, it will almost definitely see and hone in on the flower rather than the trap. Flowers are designed to attract pollinators that are adapted to identify them. The flowers exhibit ultraviolet patterns which appear as bulls-eyes to a pollinator that sees more of the UV spectrum. http://www.dailymail.co.uk/sciencetech/article-473897/A-bees...
