Album of Lynden Field Trip

Selected photos by Rod Crawford and Laurel Ramseyer from our 2 May 2018 spider collecting trip to 4 sites in and around Lynden, Whatcom County, Washington. We visited the Northwest Washington Fairgrounds, a marsh tract along Fish Trap Creek, Bender Fields Park, and an old river-access point on the Nooksack River. Part of the idea was to intercept recent European imports moving down from Canada, and our cup ran over; non-native species predominated in most samples, though all had been recorded from Washington before. Laurel was lucky enough to intercept her pet introduced species, crab spider Ozyptila praticola, expanding its range "in real time." The only good native-species records were from the marsh tract. In all we took 33 species, 15 of them non-native. Don't miss Laurel's account of the day too!
