Sampling comments: "The investigation was conducted... during August 2006 - January 2007... There were selected three consecutive transects of 550 m long and 15 m wide each. The first transect was placed in a primary forest zone, the second one in a border zone (Taking 75 m in and 75 out of the border middle line) and the third one was located in a grassland zone. Two samples were taken one month apart. Butterflies were collected using hand nets... The sampling effort was of eight hours per habitat for a total of 42 hours by sampling month. Specimens were identified using a single code and released in the same capture place, only the rare species (when necessary) were preserved"
