Picture 4 of 34

Within a month or so, these dead larvae dry down to brittle scales that are almost black. Each scale contains as many as 100 million AFB spores. The scales lie flat along the lower walls of the cells with the rear portion curving part way up the bottom of the cell. House bees have difficulty removing the scales from the cells.
