It just makes scents
The male bees are so focused on collecting scented compounds that they can easily be attracted by setting out any kind of smelly oil in the jungle. An orchid that could exploit such a drive would be able to attract an abundance of pollinators. That is precisely what Stanhopea and Catasetum orchids have done. The flowers provide a surface covered in smelly volatiles inside a strangely contorted set of petals. The petal arrangement is such that any euglossine bee that flew in to collect his perfumes would rub up against the pollen and take it with him when he leaves.
Other interesting facts about euglossine bees:
There is a species that is attracted to and even collects large amounts of DDT (dichlorodiphenyltrichloroethane) insecticide with no apparent problems.
Also, if you are a fan of The Big Bang Theory, you may have heard that a new species of bee was named Euglossa bazinga. True fact.
