用桉树脑、丁香酚、水杨酸甲酯、肉桂酸甲酯和乙酸苄酯在哥斯达黎加低地落叶林中和热带雨林中吸引雄蜂，发现不同季节雨林吸引蜂的种类组成和数量没有变化，但在落叶林中，丰度和物种丰富度在旱季均有所下降。在各主要森林类型中，不同生境间吸引蜜蜂的丰度和种类组成存在显著差异：河口沼泽森林和雨林开阔牧场的诱饵吸引蜜蜂的数量很少，而附近的森林林下样地较少。在阔叶林中，至少吸引了15种雄蜂，这些雄蜂在本林中显然没有繁殖种群，也不访问本林的兰花；可能它们通常会在遥远的栖息地或森林类型的其他地方找到雌性和化学资源。
By attracting male euglossine bees with cineole, eugenol, methyl salicylate, methyl cinnamate and benzyl acetate in Costa Rican lowland deciduous forest and rain forest, no indication of change in the composition and numbers of rain forest attractable bee species during different seasons was found, but within the deciduous forest both abundance and species richness declined in the dry season. Within each major forest type there were substantial differences in the abundance and species composition of attractable bees among habitats: baits in estuarine swamp forest and open pasture in the rain forest attracted very few bees as compared with nearby forest understory sites. In the deciduous forest, at least 15 spp. of male euglossine bees were attracted that apparently do not have breeding populations in this forest and that do not visit orchids in this forest; probably they normally find females and chemical resources elsewhere in distant habitats or forest types.
