Checklist of - Entomological Society of Canada

Leiodidae
or small carrion beetles, are more elliptical in body
shape and feed on carrion or dung. Some species are
specializecl occupants of ant nests, caves (but not in
Canada), rr the nests and burrows of vertebrates.
Members irf the Leptininae family (= Leptinidae), or
mammal rrest beetles and beaver beetles, are nest
scavengers and ectoparasites on small mammal
hosts or on beavers.
Collec;ing Leiodidae usually requires a concentration
on the particular habits or habitats of the
genera or species sought. They can be collected in
the following ways: in baited pitfall traps; by sifting
and Berlese extraction of litter or fungi; by sweeping
forest vegc,tation on still, warm, and humid evenings;
and by use,, of large-area flight intercept traps.
The leiodid fauna of Canada and Alaska is only
partly known. Several genera have been reviewed
and revised recently, and others are being prepared.
No single publication treats the entire fauna, but a
generic review of the North American fauna is
available (Peck 1990). The largest faunal works
(Hatch 1933, 1957; Jeannel 1936) are no longer
completely reliable. Distributions and bionomics of
the species are usually incompletely known, and
many species in the northern United States may
eventually be found in southern Canada.
