This native species was previously recorded in Canada only from British Columbia (Bousquet et al. 2013), but it is known to occur in several states in eastern United States ( O’Brien and Wibmer 1982). The British Columbia specimen (CNCI) was collected on spotted water-hemlock, Cicuta occidentalis Greene (now Cicuta maculata L.) ( Apiaceae).
