Insects of Cedar Creek
Order ENTOTROPHI
(Diplurans)
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.
