Sampling comments: "Four [cow dung] baited pitfall traps situated 30 m apart" (array configuration unclear); "The trap contents were collected one week later and the dung renewed three weeks later for a further sampling period, which was repeated throughout the year" (apparently meaning that there were week-long sampling periods every four weeks over a year, i.e., a total of 13 weeks)
separate data are given for each of the 12 months in 2006 but sample sizes are very small, so the totals are used
