Re: Staggering bee
It could be, or it could be any of several that affect honey bees. Tracheal mites causes crawlers, as does Nosema. The Hairless Black Syndrome form of Chronic Bee Paralysis Virus causes bees to look shiny or greasy. I see it when a colony is very stressed, but if the colony is fed, and a frame or 2 of sealed brood is given to strengthen it, then usually it does no damage.
There is no treatment for any of the viruses, just try to keep the colony well nourished and control the varroa mites. Watch out for the colony going queenless and usually thing work out ok.
