Pollen-feeding behavior of diverse insects on Geranium delavayi, a flower with large, accessible pollen grains.
American journal of botany(2023)
摘要
Our results indicated that large bees took nectar but little of the nutritionally poor and highly toxic pollen. These data support one prediction of the pollen-feeding hypothesis, that species with few and large pollen grains would also have low pollen-consumption rates.
