insect

I got out my 30 year old Magic Mill wood stone wheat grinder, after not being used for at least 8 years.  It was stored in the laundry room, and I had stupidly left about a half teaspoon of hard red winter wheat flour in the collector (& stone grinding area).  I was surprised to find about 8-10 of these dark brown/black appearing larvae still alive and moving around after all this time.  They are about 1/2" long, and I took these photos with a digital microscope, so they look larger than life.
