tefer, i suspect they have russian genetics because the hive kept a viable queen cell all the time last year. they were sold to me as open bred glenn apiaries vsh, blah, blah, blah.
hjohn, they don't really meet my standards for hot. hot to me is so many stings that you can't work them because you can't scrape stingers out fast enough. more like what alicia described.
homestead, that's why i shared what i wear. long sleeves would eliminate about 2/3 of the stings. for some reason they target my arms more than my hands.
ray, that's how i see it. someone leaning more toward commercial or sideliner would probably buy queens that put out bees that are a bit more defensive. i'm going to graft off of her but i'm going to be careful about what yards her daughters go to.
