Invasive alien predator causes rapid declines of native European ladybirds
This study compares the distribution and abundance of formerly common and widespread native ladybirds before and after the arrival of Harmonia axyridis, a globally rapidly expanding IAS. Expand
Decline in native ladybirds in response to the arrival of Harmonia axyridis: early evidence from England
1. Harmonia axyridis (Coleoptera: Coccinellidae) is an invasive non‐native ladybird in Europe, where it was introduced as a biological control agent of aphids and coccids.
Lessons from lady beetles: accuracy of monitoring data from US and UK citizen-science programs
Citizen scientists have the potential to play a crucial role in the study of rapidly changing lady beetle (Coccinellidae) populations. We used data derived from three coccinellid-focusedExpand
The harlequin ladybird, Harmonia axyridis: global perspectives on invasion history and ecology
An overview of the invasion history and ecology of H. axyridis globally with consideration of future research perspectives is provided. Expand
Agricultural Management and Climatic Change Are the Major Drivers of Biodiversity Change in the UK
It is found that species’ population change has been most strongly impacted by intensive management of agricultural land and by climatic change and a novel, flexible framework is presented that reviews evidence for the relative importance of these drivers of change and uses it to explain recent alterations inspecies’ populations.

A Vision for Global Biodiversity Monitoring With Citizen Science
Abstract Global biodiversity monitoring is urgently needed across the world to assess the impacts of environmental change on biodiversity. One way to increase monitoring is through citizen science.Expand
The harlequin ladybird, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) is an aphidophagous coccinellid, native to central and eastern Asian (Kuznetsov, 1997). This predatory ladybird has beenExpand
Rapid spread of Harmonia axyridis in Chile and its effects on local coccinellid biodiversity
Citizen science, alongside professional surveillance, has provided an effective method for studying invasion by H. axyridis, which is now well established and distributed across Chile, and has become the dominant species in alfalfa, with a concomitant decrease in species richness and diversity of co-occurring species.

Ten years of invasion: Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) in Britain
Harmonia axyridis was first recorded in Britain in 2004 and two subsequent earlier records were received from 2003, making it one of the first records of its kind received in Europe. Expand
Ladybirds (Coccinellidae) of Britain and Ireland
This atlas describes the distribution of ladybirds in Britain, Ireland, the Isle of Man and the Channel Islands, using data collated through the Biological Records Centre Coccinellidae Recording Scheme (including the UK Ladybird Survey) since 1964. Expand
