There’s been a lot of social media posts recently advocating making bee feeders and leaving out sugar water for bees. For lots of reasons this is a really bad idea (please see previous blog https://www.thelittlehoneybeecompany.com/blog/read_185365/why-leaving-sugar-water-out-for-bees-is-such-a-bad-idea.html ).
Sugar water will give bees a quick energy boost so is still good to revive a tired bee, but it doesn’t meet all their nutritional needs. They need nectar and pollen, both of which are provided by flowers in varying quantities. That means bees are vegetarian.
