Family GEORYSSIDAE minute mud-loving beetles
R.E. Roughley
Georyssidae includes minute beetles, usually
under 2 mm long; two species are known for the
Nearctic region, one of which occurs in Canada.
Adults are found in mud or sand at the edges of
streams and are often concealed by sand grains or
mud attached to the body; they are apparently algal
feeders.

Family HISTERIDAE hister beetles
A. Dauies
In Canada and Alaska 118 species of Histeridae
have been recorded. The adults and larvae are chiefly
predators of other insects and their larvae. Most
species are associated with decaying organic material,
dung, and carrion; some are found in sandy areas, in
mammal burrows, under bark, and in bark-beetle
galleries; a few are myrrnecophilous. Although some
species are associated with stored products, they most
likely feed on other insects that occur there.
LeConte (1845), Marseul (1853-1857, 1860-1862),
and Horn (1873) have conducted major taxonomic
treatments of the North American Histeridae. The
classification used here is based on Arnett (1968),
whereas the status of the species is based on Mazur
(1984) and on work by Helava (personal communication).
