Studies on the biology of Collops vittatus (Say) were undertaken in the laboratory and field at Tempe, Ariz., from June 15 to September 15, 1957. On an average 78 days were required for development from egg to adult. Additional data on longevity and feeding capacity of C. vittatus in relation to temperature are given. Observations on the feeding habits of seven predators of the spotted alfalfa aphirl (Therioaphis maculate (Buckton)) indicated that the average number of aphids destroyed per adult per day by hippodamia convergens G.-M. was 97, Collops vittatus (Say) 35, Zelus renardii Kolenati 34, Geocoris punctipes sonoraensis Van Duzee 29, Sinea confuse Caudell 24, Nabis ferus (L.) 22, and Orius tristicoler (White) 5. The effect of sex and different feeding periods on the feeding capacity of the various predators is also given.
