Non-floral scent sources of orchid bees

We observed male euglossines collecting scent at 21 different non-floral sources in Central and South America, strengthening the view that these sources play a central role in euglossine perfume biology. A \(\it Protium\) tree provided over 50% of the perfumes for \(\textit {Eufriesea corusca}\) and was repeatedly revisited. The co-occurrence of females collecting resin suggests an evolutionary link to male perfume-making.
