Insects of Cedar Creek



     The Entotrophs (64 NA spp) are generally less than 10 mm long, slender, soft-bodied, with long many-segmented antennae, no eyes, wingless, and with terminal cerci.  They occur in decaying vegetation, damp soil, etc.  Some feed on vegetable matter while others are predaceous on Collembola, mites, etc.  Four families occur in North America, but only two (Campodeidae, Japygidae) are likely to be found in Minnesota. The Campodeidae have long 10-segmented cerci.  A common species of humus in damp woodland is Campodea folsomi.  The Japygidae have dark, heavily-sclerotized, forceps-like cerci. Catajapyx disversiunguis is a fairly common soil-inhabiting species.  None collected at Cedar Creek.
