Mitigating the precipitous decline of terrestrial European insects: Requirements for a new strategy

Severe decline in terrestrial insect species richness, abundance, flying biomass, and local extinctions across Europe are cause for alarm. Here, we summarize this decline, and identify species affected most. We then focus on the species that might respond best to mitigation measures relative to their traits. We review apparent drivers of decline, and critically reflect on strengths and weaknesses of existing studies, while emphasising their...
