Hydroporus appalachius Sherman

Notes.

Several specimens of this distinctive species were collected at two different sites in Inverness County (samples I79, I86).

Habitat.

Hydroporus appalachius is usually found in habitats where there are some water movements either along the margins of small lakes or in small streams and springs ( Larson et al. 2000), which describe exactly the habitats where these beetles were found in Cape Breton Island.

Distribution in the Maritime Ecozone.

This species has a wide range in North America east of the Rocky Mountains. It occurs from Labrador and New Hampshire west to the northern Great Plains and north into the boreal zone and southern limits of the low artic ( Larson et al. 2000). Its presence in Cape Breton Island represents the first mention of the species in the Canadian Maritimes ( Bousquet et al. 2013).
