Western Sea Roach (Ligia occidentalis)
This is Western Sea Roach (Ligia occidentalis), Common Rock Louse
(Ligia pallasii) is more common in BC but has shorter uropods. Would you consider adding this to iNaturalist? I'm very interested in this disjunct population of L. occidentalis which occurs much further north than the rest of the species around Vancouver http://www.inaturalist.org/observations?place_id=any&taxon_id=117674
