24、粉）crops including alfalfa,carrots and melons.The European insects were introduced to North America in the 1930s for that purpose,and theyve since become wild,joining the continents many native species of leafcutter bees.In a separate study conducted in Argentina between 2017 and 2018,researchers fou
