The Belgian Coccinellidae dataset which is published, is the result of a merge of 4 datasets. The INBO (Research Institute for Nature and Forest; Flemish Region Database), the DFF database (The Walloon Region Database), Observations.be data provided by Natagora (The Walloon Region and Brussels Capital Region) and the Walloon Region Online Encoding Tool (DEMNA - OFFH, observatoire.biodiversite.wallonie.be/encodage) data. At present, the database contains about 80.000 records, of which 15% come from museum collections and literature data. Collection events minimally consist of species, number of individuals, stage (adults, larvae and pupae), observation date, observer and location. Original locations as well as collection material were attributed to 1x1 km or 5x5 km grid cells of the UTM grid (Universal Transverse Mercator). A large part of the Belgian territory has been surveyed for ladybird beetles: the database contains records for at least 85% of all 5x5km UTM grid cells (N = 1376) in Belgium
. Additionally, data on substratum plants, height in the vegetation, sampling method, habitat type, surrounding landscape, slope orientation, soil type, humidity, vegetation cover and behaviour were noted. In 1999, the Belgian Ladybird Working Group Coccinula launched a large scale field survey on 40 native ladybird species (Coccinellinae, Chilocorinae and Epilachninae) and to date has more than 500 volunteers providing distribution data. They actively search for ladybird beetles in a variety of habitats using sweep nets, beating trays, visual search, light trapping, pitfall traps and other sampling methods. Distribution, habitat and substrate plant information is also noted on a standard recording form. The working group maintains a database of observations, literature and collection data of Coccinellidae from 1800 onwards. Preliminary atlases have been published for the whole Belgian territory (Branquart et al., 1999; Adriaens and Maes, 2004) and updated distribution maps are available online, on demand and through the working group's newsletter. The published dataset contains most of the data maintained by the working group. For the time being, only the original INBO database is published.
