Collection and habitat data.

Hemiquedius ferox was reported by Smetana (1971a) from various wet habitats, such as swamps, lake margins, and marshes. Adults were found in wet moss and leaves and in beaver lodges in late fall. Adults were found in similar habitats in New Brunswick, including an alder swamp, silver maple ( Acer saccharinum L.) swamps, pond margins, a seasonally flooded marsh, a gravel bar on river, and a beaver lodge. Adults occurred in moss and Carex hummocks, in leaf litter along vernal pond margins and within the wall of a beaver lodge. Adults were collected by sifting litter and moss or treading vegetation into water. One individual was collected in a Lindgren funnel trap. Adults were captured during May, June, July, August, and September.

Distribution in Canada and Alaska.

ON, QC, NB, NS ( Smetana 1971a). It is apparent from the above records that Hemiquedius ferox is more widely distributed in the Maritime provinces than was suggested by the collection records reported in Majka et al. (2009).
