Three species of Cupedidae occur in Canada.
This small, primitive family of beetles contains only
30 extant species around the world, but it is well
represented by fossils dating back to the early
Triassic. l,ittle is known about the biology of the
species-the larvae apparently bore into wood, and
the adults iue collected from foliage or under bark.
The farnily Cupedidae is well known taxonomically.
Atk.ns (1963) revised the world species, and
Neboiss (1984) the species of Cupes. Ponornarenko
(1969) discussed the fossil origins of the Coleoptera
with particular reference to the srrborder
Archostemata and the family Cupedidae, rerviewing
the fossil and extant species of the family. Atkins
(1979) cataloged the North American taxa of the
family.

Family MICROMAL'THIDAE telephone-pole beetles
J.M. Campbell
This fz: mily contains only one species, which
was descri ced from the eastern United States but
has subserluently become established in western
Canada, C uba, Brazil, Hawaii, Hong Kong, and
South Afrir:a. The larvae are wood borers and are
found in decaying oak logs and in moist, creosotetreated
timbers and poles. The life cycle of
Micromalthus debilis is one of the most complex
known to occur in Coleoptera. The larvae are paedogenetic,
producing either living larvae or a single
egg that develops through a different larval type to
produce an adult male (Pringle 1938).
Atkins (1982) cataloged the species for North
America.
