Scientists have developed a breakthrough food supplement that could help save honeybees from devastating declines. By engineering yeast to produce six essential sterols found in pollen, researchers provided bees with a nutritionally complete diet that boosted reproduction up to 15-fold. Unlike commercial substitutes that lack key nutrients, this supplement mimics natural pollen’s sterol profile, giving bees the equivalent of a balanced diet.
I researched that, maybe it’s just in Australia but apparently the bees here don’t use those bee hotels? They apparently just get stacked with earwigs. I read the best thing you can do for bees here is plant native flowering plants like the Bottle Brush, and let leaves biodegrade naturally instead of hoovering em up.
