Between February 1960 and December 1961 observations were made on the desert grasshopper (Trimerotropis pallidipennis pallidipennis (Burmeister)) at Mesa, Arizona. Average and maximum adult longe\'ity were 52.9 and 138.0 days, respectively. The average number of eggs per ovipositing female was225a,nd maximum production by a single female was 955 eggs in 27 pods. During July and August, eggs hatched in an average of 15.5 days. In late winter and early spring the average nymphal period was 53.5 days and at high summer temperatures, 32.2 days. It seems probable that this grasshopper could complete a generation in about 3 to 3½ months during the summer.
