Adults of the flea, Ceratophyllus vagabundus vagabundus, were present in the hundreds in nests of Ross's (Chen rossii) and lesser snow (Chen caerulescens caerulescens) geese in the Arctic goose colony at Karrak Lake, Nunavut, Canada. Ceratophyllus v. vagabundus had not been previously recorded in association with Ross's or snow geese. Large numbers of C. v. vagabundus adults and larvae were collected and a description of the larva is provided for the first time. On the basis of external characters, larvae were indistinguishable from those of a number of other Ceratophyllus spp. previously described from North America, i.e., Ceratophyllus idius, Ceratophyllus niger, and Ceratophyllus lari.
