Sampling comments: "23 sites... were located within 35 km of each other... At each site, a 10 m by 10 m subplot was established... Sites were sampled... six times... between the last week of June and the first week of September... A sweep net sample was taken, using an insect aerial net with a four foot handle, in the vegetation surrounding the 10 m by 10 m sampling plot... An equal number of 150 sweeps were taken" (presumably meaning 150 sweeps x 6 sampling events x 23 sites = 20700 sweeps)
