Extract

During a study on the importance of spiders as predators of the cabbage butterfly Artogeia rapae L. (Lepidoptera: Pieridae) in cultivated cruciferous fields in Quebec, 209 specimens (114 were immatures riding on the back of a female) of Trochosa ruricola (DeGeer) (Lycosidae), 21 specimens of Ostearius melanopygius (O. Pickard-Cambridge) (Linyphiidae), and one specimen of Dictyna decaprini Kaston (Dictynidae) were found by pitfall traps and aspirator at L'Acadie, Quebec (45°20'N, 73°20'W) in cabbage, Brussels sprouts, and broccoli plots. This is the first record of these species in Canada.
