From 1997 to 1999, 11435 specimens of ground beetles representing 124 species were trapped at two commercial vineyards in southern Québec. Considering only species breeding or likely breeding at these two vineyards, we found that the diversity was similar over the three-year period within each vineyard. Though the number of species was similar (51 and 54 species respectively) between the two vineyards, the most commonly trapped species were ranked differently for most species, and some of the dominant species were characteristic for each vineyard. i.e. Chlaenius sericeus (Forster) and Clivina fossor (Linné) on the clay loam vineyard, and Amara latior (Kirby) and Harpalus herbivagus Say on the gravel and sand loam vineyard. The rank position of the most commonly trapped species at each vineyard was generally consistent over the three-year period. Two European species, one recently introduced and another recently established in southern Quebec became more prevalent between 1997 and 1999 and will probably affect the rank position at each site. The Shannon-Wiener diversity and evenness indexes were clearly greater at the gravel and sand loam vineyard than at the clay loam vineyard
