Abstract
An identification key based on French ladybird colouration is proposed for the tribes Chilocorini, Coccinellini, and Epilachnini. These tribes were chosen based on their relatively limited species diversity, as well as their large size and high colour diversity, making them easy to observe and collect. The identification key runs on Xper(3) software, which allows the building of structured knowledge bases and online free-access keys. The online interactive Xper key is available at http://french-ladybird.identificationkey.fr.
