Family STAPFIfl INIDAE rove beetles
J.M. Campbell and A. Dauies
The role beetles form one of the largest families
of insects in the world, with over 32 000 described
species. ,[n Canada, ll29 species have been
reported, b,ut hundreds more remain to be either
described or recorded. Most rove beetles are predators
of oth,:r insects and live on or in the soil, in
ground litt*:r, moss, or in decomposing organic matter.
Some r:ove beetles prey on aphids, bark beetles,
or other ir.sects on trees and herbaceous plants,
whereas others are specialized feeders on pollen or
are myceto rhagous. Rove beetles prefer moist habitats
along t,he margins of streams, lakes, and snowfrelds,
and in decomposing vegetation, manure, and
carcasses. They are common in all biomes, ranging
from tropical forests to tundra well above arctic and
alpine timberlines. Some species are associated
with mammal burrows, ant and termite nests,
intertidal and coastal habitats. and saline flats:
they can also be found in a variety of habitats
around human dwellings.
Several authors are currently investigating the
higher classifrcation of the family. The system fol-
Iowed in this checklist has been extensively modified
from the conventional system used in earlier
papers. The system is based primarily on a paper
by Lawrence and Newton (1982), but will uindoubtedly
be modifred further as more phylogene bic studies
are completed. Adults of most genera of rove
beetles (except the genera of Aleocharinae) can be
identifred with the use of keys by Arnett (1968) and
Moore and Legner (1974 and 1979) or with keys
based on the European fauna such as those ofLohse
(1964) and Lohse et al. (1974). Most larvae have
not yet been described. Newton (1990) provides keys
to the North American genera of larvae and adults
that inhabit soil litter. Other Nearctic genera can
