Well, bees don't invent controlled experiments to test our symbolic reasoning, think through the results, form philosophical questions using arbitrarily complex language structures, and post them on the own worldwide information-sharing networks they invented. So I'd say there's a pretty big gap.

Assuming that intelligence can be quantified, and that extremely higher values are physically possible, yes, the orders-of-magnitude difference between bees and humans might theoretically be dwarfed by some other comparison. Just like the size difference between a grain of sand and a mountain is not significant compared with the difference between the mountain and the Milky Way. But it's still a massive (get it?) difference.
