91% Informative

University of Alberta study: Treed field borders supplied more than 33 times more hoverflies to canola fields than grassy borders.

The family of flies move between the fields and their borders, feeding on nectar and pollen from blooming crops.

In the process, they pollinate the crops, which can boost yield.

Their larvae often feed on soft-bodied crop pests like aphids and thrips.

More information: Rachel Pizante et al, Treed field borders net-export over 82,000 more hoverflies per km every week into canola crops than herbaceous field borders, regardless of mass-flowering crop bloom, Agriculture, Ecosystems & Environment ( 2024 ).
