Habitat comments: " 50-100 yr old secondary regenerating deciduous forest near the bat cave along the nature trail by the Casona; in the semievergreen forest on the escarpment -3 km northeast of the main administration area (selectively logged in the 1940's); and in the oak forest-grassland edge at the top of the escarpment looking northwest over a large deciduous forest 1 km north of the semievergreen forest... annual rainfall ranges from 1400 mm to 2200 mm, with a mean of -2000 mm... The last days of rainfall usually occur in late December and the first rains fall sometime between the last week of April and the middle of May"

Sites: 6
Sampling methods: line transect, baited, other traps
Sample size: 67
Years: 1977
Seasons: dry
Nets or traps: 5
Sampling comments: "Cineole, eugenol, methyl cinnamate, benzyl acetate, and methyl salicylate were selected as the baits... 16-cm2 squares of heavy blotter paper were soaked in a compound and each square placed individually in a small plastic bag that was then knotted shut. At the census site, each of the five bags was pinned to a different tree trunk in shade - 1.5 m above the ground. The five trees were chosen so as to be about eight to 15 paces apart and arranged in a roughly straight line or shallow arc"
