The Proturans (20 NA spp) are poorly known.
They are less than 2.5 mm long, bristly, and lack antennae and eyes.
Their forelegs project forward and function as antennae. They occur
in humus and rotting vegetation. Three families (Eosentomidae, Protentomidae,
Acerentomidae) occur in North America, and representatives of all may occur
in Minnesota. None collected at CCNHA.
