Eulaema meriana is a large-bodied bee species in the tribe Euglossini, otherwise known as the orchid bees. The species is a solitary bee and is native to tropical Central and South America. The male collects fragrances from orchid flowers, which it stores in hollows in its hind legs. Orchids can be deceptive by mimicking the form of a female and her sex pheromone, thus luring male bees or wasps. Pollination will take place as the males attempt to mate with the labellum, or the tip petal of the flower. Male E. meriana are territorial and have a particular perch on a tree trunk where it displays to attract a female. After mating, the female builds a nest with urn-shaped cells made with mud, feces, and plant resin, and provisions these with nectar and pollen before laying an egg in each. These bees also have complex foraging and wing buzzing behaviors and are part of a mimicry complex. Description Eulaema meriana resembles a bumblebee in appearance and is covered in short dense hairs. At first glance Eulaema bees look like large bumblebee queens. They are relatively large bees with faint metallic colorations. The head of the bee is black, and the thorax brownish black with a large, glossy black scutellum. Their abdomen is black with three transverse pale yellowish bands on the anterior half, and the posterior third is reddish brown. E. meriana also possess membranous wings that are dark at the base and paler at the tips. The legs are black and the tibia of the hind legs are much thicker. Males possess hollows on their hind legs, while females have pollen baskets. In general, the species have long tongues that are thought to be an evolutionary adaptation that favors nectar collection. The large body size is thought to allow the bees to fly in cooler, rainy conditions and continue foraging. It has also been suggested that the larger body size can help them forage for longer distances. Taxonomy and phylogeny Eulaema meriana are part of the order Hymenoptera, which includes ants, bees, wasps, and sawflies. More specifically, they are in the bee family, Apidae. E. meriana are part of the Euglossini tribe within the subfamily Apinae. Euglossini are part of a group known as corbiculate bees, a group that also includes honey bees, stingless bees, and bumble bees. Members of this group have depressions on their hind legs that
