The easiest way to tell the “good bees” from the “bad bees” is by their appearance. The good bees are typically yellow-orange in color, while the bad bees are typically black or dark brown. Additionally, the good bees will often have a more pronounced “wasp waist” – a characteristic that is caused by their elongated abdomen and shaped like that of a wasp. Finally, the good bees will be busier than the bad bees, as they are responsible for filling up ecosystems with their pollination services.
