The early emergence of mason bees is likely due to the higher-than-average, extended summer temperatures we had in the summer and fall of 2022. When we have higher-than-average summer temperatures, the speed of development increases, and the new bee becomes an adult quicker than usual. Once the bee becomes an adult, it shifts...
