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"
Methods
Life forms: orchid bees
Sites: 6
Sampling methods: line transect,baited,other traps
Sample size: 217 individuals
Years: 1977
Seasons: wet or monsoon
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"
