Age-dependent perfume development in male orchid bees, Euglossa imperialis
Journal of Experimental BiologyABSTRACT Male neotropical orchid bees concoct complex perfume blends by collecting exogenous volatiles from various sources, including orchids. These perfumes, stored in specialized hind-leg pouches and released during courtship, serve as inter-sexual signals.

Three‐dimensional visualization of ocellar interneurons of the orchid bee Euglossa imperialis using micro X‐ray computed tomography [PDF]
Journal of Comparative Neurology, 2017 AbstractWe used contrast‐optimized micro X‐ray computed tomography (mCT) to trace the profiles of the full complement of large ocellar L‐neurons in the male orchid bee Euglossa imperialis. We find that most L‐neurons collect information from either the dorsal or the ventral retinae in both median and lateral ocelli, with only three neurons associated ...

Mechanics of nectar feeding in the orchid beeEuglossa imperialis: pressure, viscosity and flow [PDF]
Journal of Experimental Biology, 2006 SUMMARYThe orchid bee Euglossa imperialis sucks nectars through a slender proboscis. I tested how nectar properties influence this suction pressure and whether ambient air pressure sets the upper limit for suction feeding. Nectar intake rate was measured as a function of sucrose concentration (5-75% w/w),nectar viscosity (2-80 mPa s), and ambient ...
