Male Euglossini bees (Apidae) forage for floral and non-floral perfumes. Although the use of these perfumes has not yet been clearly reported, there are indications of using perfume from varied exogenous sources as a pheromone analogue since male orchid bees do not produce it. Here, we report an interaction between male Euglossa annectans and flowers of Angelonia salicariifolia (Plantaginaceae). Floral anatomy analysis and a histological study of two different sets of trichomes indicate the presence of aromatic oils (perfume) in one set of these trichomes. The other set of trichomes produce resins. Both sets of trichomes are found in the same floral area of the flower where the male orchid bees were seen. The male orchid bees studied forage for perfumes but do not promote pollination since they do not reach the reproductive structures during their visit. Our records show that only male E. annectans were attracted to the volatile fragrance although we know that other orchid bee species also occur in the area.
