	Folsom Era Weevils These weevil abdomens were found in a Folsom era archaeological excavation near Gunnison, CO in the fall of 2006. Several hundred of them were found in a rock wall that was buried about 18" below the soil surface. They are in excellent condition considering the archaeological evidence suggests they may be 10,000 years old! They have been identified as Dyslobus (near) wasatchensis, a root weevil that is possibly an undescribed species. For more information on the Folsom site, click here.
	Sphaeralcea weevils These Apionid weevils were found attacking seed production fields of scarlet globemallow at Hotchkiss, CO in May 2007. This page contains photographs of all life stages and the most up to date information we have on the insect.	The Sphaeralcea weevil (html)
