Larva (Rodent Bot fly)

/in /by

#5475  This was found on my laundry room floor in Boulder Colorado just now.  It’s a little over an inch long, dark brown and ringed, with a yellowish “nose.”  It’s creeping very slowly.  What the heck is this?
This is a mature larva/prepupa of a rodent bot fly (Diptera: Cuterebridae; Cuterebra sp.) – see  http://tinyurl.com/naggfdc for images and more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.
