In 1995-1996, John Goold was gathering data on the daily activity patterns of Odonata. He made collections at various times of the day and in different weather conditions to help determine under what condition dragonflies fly. Johnalso used data collected by Dirk Westfall and Chris Todd. John found strong correlations between light intensity and temperature and the number of dragonflies which were active (there are more dragonflies out on warm or sunny days).
