Ladybirds conquering the world
The arrival and subsequent dramatic increase in the number of the invasive alien harlequin ladybird in many countries has been met with considerable trepidation by the scientific community.
“The rapid spread of this species has inspired biologists to study the process of invasion on a global scale,” says Helen Roy of the Centre for Ecology & Hydrology in the UK. She is the lead author of a paper¹ in Springer’s journal Biological Invasions that includes the insights of researchers from 45 institutions worldwide about related global research endeavours. The paper is part of a special issue² just published on insect invasions.
