Ascosphaera callicarpa

Ascosphaera callicarpa is a fungus common on the larval feces of the solitary bee Chelostoma florisomne, which nests in the Phragmites reeds of thatched roofs in Europe. Pathogenic Ascosphaera species afflict only the larval stage of bees. Typically, diseased larvae die in the larval stage; in rare occurrences, however, larvae have been observed to enter pupation before being overcome by the fungus.
