Re: Bees Bringing in Fungus in place of pollen
Randy Oliver's response to the same question on Bee-L.
What is the nutrition of Pucciniastrum epilobii (Fireweed Rust) or rust
> spores in general vs pollen?
The "fried eggs" that Dr. Eric Mussen and I observed in bee guts during the
CCD epidemic turned out to be *Uromyces* rust spores (search "fried eggs"
at my website).
In my area, such spores can constitute 100% of the beebread in late
summer. Colonies quickly go downhill on that diet.
When this happens, we feed 2.5 lbs of high-quality pollen sub per hive
every 10 days, which immediately turns the colonies around, and gets them
into good condition for winter.

Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
