It's not particularly new, this is just some new work on how extensive moth pollination can be. Bees are most definitely not the only or "most important" pollinators. In an economic sense for the US the most important pollinator is technically the wind because we grow corn, and lots of plants are only pollinated by specific moths/flies/wasps. And the European honeybee in particular (the one we keep worrying about with colony collapse and everything) isn't even native to the US. Even among pollinator requiring crops, those things classically seen as being the domain of the bee, as much as 39% of flower visits are non-bee pollinators. [0]
