Sampling comments: "Collection took place from June to August 2003 and from September 2004 to May 2005... pitfall traps were placed at least one week before the start of sampling to avoid 'digging-in' effects... One sampling event per month took place (12 sampling events in total)... a line transect of 70 m was established. Eight pitfalls were spaced at 10 m intervals along the transect. Each group of pitfalls (56 traps in total) was located at least 230 m from another group... All traps were left open for five days per sampling event"
