Insects of Cedar Creek
Order DERMAPTERA
(Earwigs)
The Earwigs (20 NA spp) have short wing covers, and workable forceps at
the end of their elongate abdomen. They are gregarious omnivores
and occur in flowers, humid crevices, under bark. Females of some
species tend their eggs and young. Five families occur in NA and
most species are southern in distribution. However, representative
of two families (
Labiidae--Labia minor;
Forficulidae--Forficula
sp, Doru sp) have been collected in Minnesota. Undetermined Earwigs
crawled into my tent poles at Blue Mound SP in SW Minnesota. A single
earwig,
Forficula auricularia, an introduced species, was
collected while cleaning my car at CCESR. Origins unknown.
