      A brief review of the American Southwest Hemileuca (Buckmoth) group is presented with a discussion of Southwestern biotic communities and habitats and the interrelationship of Buckmoths to these habitats. Food plants used by larvae of the various species in the specific habitats are reported together with photos showing larvae on associated food plants.

    • Chollas, Circles and Seris: Did Seri Indians Plant Cactus at Circle 6

      Bowen, Thomas; Felger, Richard S.; Hills, R. James; The Southwest Center, University of Arizona; Drylands Institute; Arizona-Sonora Desert Museum (University of Arizona (Tucson, AZ), 2004-12)
      On November 26, 1966, during an archaeological survey, one of us (Bowen) and Stephen D. Hayden discovered a circle of stones on Punta Santa Rosa, a prominent point of land on the coast of mainland Sonora, Mexico (Figure 1 ). This in itself was not remarkable because they had encountered other circles previously. What was noteworthy was that this particular circle was surrounded by a ring of small jumping cholla cacti (Cylindropuntia fulgida var. fulgida) that seemed obviously planted. Punta Santa Rosa lies within the historic territory of the Seri (or Comcaac) Indians, and Bowen and Hayden knew that the Seris had used stone circles as part of the traditional vision quest. But since the Seris were considered a nonagricultural hunting-gathering-fishing people, the association of a presumably Seri circle with cacti that appeared intentionally planted seemed incongruous. At that time, however, Bowen and Hayden did nothing more with this odd feature than photograph it, give it the prosaic designation "Circle 6", and pass it off in an archaeological report as probably just an unusual Seri vision ring (Bowen 1976: 40). They did not anticipate that Circle 6 would continue to pose an ethnobotanical puzzle and one day provide an object lesson in archaeological interpretation. But puzzle it was. In this paper we reexamine Circle 6 in light of the known history of Seri planting. We consider several hypotheses, some of them proposed by modern Seris, about the circle's age, cultural identity, and function. We conclude that the original interpretation of Circle 6 as a vision ring is incorrect but that the peculiar cholla ring most likely does constitute a case of purposeful Seri planting.
