Why does the lack of specialized hair in *Hylaeus* reinforce the need for internal pollen mixing?
Answer
They are not effective at picking up and carrying large quantities of dry pollen incidentally
The yellow-faced bee possesses minimal hair, making them look somewhat wasp-like. This lack of dense, specialized hair means they are inefficient at picking up and retaining large amounts of dry pollen incidentally while foraging, unlike fuzzy bees. This physical limitation underscores why their survival mechanism relies heavily on the deliberate act of mixing pollen with nectar internally before storing it. They must actively collect the necessary components rather than relying on passive transfer during flower visits.
