Notizen: Summary In situ trapping efficiencies of Pinguicula alpina L., P. villosa L., and P. vulgaris L. were compared with each other and with those of artificial traps at a subarctic site in northern Sweden. P. vulgaris had the highest trapping efficiency i.e., 21–37 μg prey trapped cm-2 day-1 and apparently has some means of attracting prey. The other two species trapped about 14–18 μg cm-2 day-1, a value similar to that of paper traps mimicing plant leaves. By weight, Nematocera and Collembola were the dominant groups trapped by P. alpina. P. villosa trapped mainly Collembola, while small Nematocera dominated the prey caught by P. vulgaris. Mites (Acarina) were caught in high numbers but contributed only a small part of the total captured biomass owing to their low weight.
