Abstract/Contents:"Scapteriscus acletus Rehn and Hebard and S. vicinus Scudder were accidentally introduced to the United States from South America, and between 1920 and 1960 they spread from northernmost to southernmost mainland Florida, a north-south distance of 600 km (= 5.7° lat.). Latitudinal variation in the life cycles of these recently established populations was studied by monitoring seasonality of flight for 1 to 3+ years at nine stations in peninsular Florida. Flights of both species generally showed a large spring peak and small fall peak annually, with the fall peak of one year and the spring peak of the next attributable to a single generation of adults. Geographical variations in S. vicinus flights were minor, with the median cricket of both spring and fall flights captured at stations in north Florida several weeks later than in south Florida. Flights of S. acletus were likewise similar along the latitudinal gradient, except that at three stations in south Florida a summer peak of flight occurred that rivaled or exceeded the spring and fall peaks. This suggests that S. acletus has, in less than 40 years, made the transition from one to two generations per year, a latitudinal change that is rare in native eastern North American crickets."
