Carabid beetles were trapped in summer 1987 and spring 1988 in the Plateau des Tailles (ProvinceLuxembourg, Belgium). The traps were checked every morning during 10 trapping sessions (79 days). Temperature and humidity were recorded continuously on the site during the whole period. The influence of these two meteorologica 1 variables was studied using a Stepwise Linear Regression Model in order to study the informationadded by the different variables. ln spring, the higher the Mean daily temperature, and the lower the day-night temperature contrast and the Mean daily humidity, the more Carabus problematicus and C.auronitenswereactive. The activity of Carabus problematicus and C.auronitensin summer, and of C.violaceusinspring was positively correlated with the Meandally temperature.C.violaceusis active in spring mainly in nights during which the humidity at midnight is between 85 and 97%.
