Although I sampled in Arlington in October 2015, I considered the city under-sampled since I had only tapped one full set (50 cones) and one partial set (13 cones) of cones there. Further, the partial set of cones had been lying in tall grass, a situation that I've found to be unattractive to O. praticola in western Washington. So I returned to Arlington in search of at least one more set of more suitably situated cones to tap.

At present, Arlington is the northern edge of O. praticola's known range in western Washington. The search will continue...
