Caddis that may be here. Found in contiguous or nearby high elevation Colorado Counties

Based on comparisons with data from other counties, it appears the highest elevations of Gunnison County may be poorly collected.

  • Cheumatopsyche pettiti (Banks) 1908 (HRU Lower Gunnison - " ")
  • Chimarra utahensis Ross 1938 (Montane, warm spring/Park county)
  • Culoptila thoracica (Ross) 1938 (High elevations, Eagle, Summit, Grand)

     Quote " If these remarks appear to entomologists well founded, and it be thought right to consider Phryganea as constituting a new order, I think it might be distinguished, since the wings of all the known species are hairy, by the name of Trichoptera. "

"The Electric Monk was a labor-saving device, like a dishwasher or a video recorder. Dishwashers washed tedious dishes for you, thus saving you the bother of washing them yourself, video recorders watched tedious television for you, thus saving you the bother of looking at it yourself; Electric Monks believed things for you, thus saving you what was becoming an increasingly onerous task, that of believing all the things the world expected you to believe." -- Douglas Adams
