bee magnet

Gardeners world info states that Euonymus Silver Queen has no known benefit to wildlife. Please can someone tell the bees then because mine is absolutely choc-a-bloc with honey and bumbles and loads of other pollinators, gorging themselves on the mass of tiny creamy white flowers. It's like this every year. Shrub is approx. 5' high and wide. Am I missing something? Are they wasting their time? Thoughts appreciated.
