Insects of Cedar Creek


(Rock Crawlers)

Rock Crawlers (10 NA spp) occur on rocks near glaciers in NW US and SW Canada.  These leathery elongate (10-30 mm) wingless creatures make a living (if you can call it that) feeding on dead insects in high altitude snowfields.  Only a single family (Grylloblattidae) with ca 20 world spp occurs in this order.  None in Minnesota or at CCESR.
1. Family GRYLLOBLATTIDAE (Not found in Minnesota)
