Insects of Cedar Creek



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.
