Bees not only contribute significantly to ecosystem biodiversity, but as pollinators they are responsible for facilitating the reproductive processes of many tropical forest plants. As tropical forests are fragmented and destroyed, euglossine bees are under increasing threat of habitat loss and population declines. Understanding their altitudinal and geographical distributions is a critical aspect needed for future conservation efforts. I sampled at four different altitudes along the Pacific slope and three different altitudes along the Caribbean slope. I used three different chemical scents: Methyl Salicylate, Eugenol, and Cineole, as baits to attract male Euglossine bees to sample their populations. The chemical Methyl Salicylate had the ...
