Common but much less so than Pusillina inconspicua, living on algae near low water and a little below, in more sheltered and sometimes muddier places. Recorded by Marshall (1897b) from Skye and Barra. Feeds on adnate bacteria and detritus. Allen (1962) listed Rissoa albella and Rissoa sarsi separately.
