One of the things you may be missing is that the article is about "efficiency" as opposed to total impact.

"researchers found that 83% of insect visits to bramble flowers were made during the day. While the moths made fewer visits during the shorter summer nights, notching up only 15% of the visits, they were able to pollinate the flowers more quickly."

Moths are doing great work, but they don't have much time to do the work in and they are not doing the bulk of the work. Also it seems that the night pollinators actually may largely work different flowers than the day pollinators so one can't necessarily pick up the load left by the absence of the other.
