Experiments with bumble bees and artificial flowers show that bees avoid visiting types of flowers that are rare and with which they have no previous experience.

Such behaviour would reduce the likelihood of early-flowering plants being pollinated, because when a species first comes into flower it is both uncommon and unfamiliar to pollinators. Simulations show that this could prevent the evolution of early flowering, which might otherwise be favoured when late-season growing conditions deteriorate.

This could cause declines in plant populations that are already facing pollinator shortages and habitat loss, and is of particular concern given future climate change scenarios.
