Recently our new publication on the importance of non-bee insects for crop pollination around the world was published online at PNAS.
We found that other insects than bees also are important for the pollination of crops. Examples of these non-bee pollinators are insects such as flies, beetles, moths, butterflies, wasps and ants. Non-bee pollinators were less effective than bees per flower visit however, they provided more visits.
As these other insects responds a bit different to e.g land-use changes than bees do, they can perhaps stabilize the pollinations service under environmental change.
Non-bee insects are important contributors to global crop pollination
