Bee health research. Entomologists checking alfalfa leafcutting bees (Megachile rotundata) for chalk brood fungus (Ascosphaera apis) infection. The researcher in the foreground is sampling the air for chalk brood fungal spores. Chalk brood fungus is thought to be spread by ingestion of the Ascosphaera apis spores. The infection kills affected bees, giving their bodies a chalky white appearance.
