The Pan-Pacific Entomologist
The Palo Verde Valley, a narrow strip of river bottom about thirty miles long lying adjacent to the Colorado River in eastern Riverside County, California, is bounded by mountains and a mesa to the north, south and west, and by the Colorado River to the east. It has a considerable acreage of cultivated areas although the greater portion of the valley consists of mesquite, tamarisk and arrow-weed thickets. Thus the valley offers a splendid opportunity for collecting a varied population of Dasymutilla in large numbers.
