These upside down basket weaving spiders (my attempt at describing their web shape) are very common in this part of the B.C. Interior. A charming characteristic is their extended courtship and mating which seems to last for days. Can you recommend a spider identification web site?

We double checked with Eric Eaton who writes: “those are most definitely bowl-and-doily spiders, Frontinella pyramitela (formerly F. communis). Great images, indeed!” We love BugGuide for identification.
