Data deficient. This flea is found in the nests of cliff swallows, sometimes in large numbers. This flea is known from only one location in the territory, Aklavik. There are recent concerns over the apparent declines in populations of aerial insectivores, and there are reports that cliff swallow populations may be declining at about 3% per year. More data are needed before an accurate rank can be assigned to this flea in NT. This flea is also present in YT and northern BC.
