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.

Diversity and Temporal Variation in the Orchid Bee Community (Hymenoptera: Apidae) of a Remnant of a Neotropical Seasonal Semi-deciduous Forest [PDF]
Sociobiology, 2015 Multiple biotic and abiotic variables control the composition, diversity, and temporal fluctuations of insect communities. In particular, the assembly of bee communities is strongly influenced by climatic factors as well as variation in food resource ...

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 ...

Are body size and volatile blends honest signals in orchid bees? [PDF]
Ecol Evol, 2017 Secondary sexual traits may convey reliable information about males’ ability to resist pathogens and that females may prefer those traits because their genes for resistance would be passed on to their offspring.

Conservation value and permeability of neotropical oil palm landscapes for orchid bees. [PDF]
PLoS One, 2013 The proliferation of oil palm plantations has led to dramatic changes in tropical landscapes across the globe. However, relatively little is known about the effects of oil palm expansion on biodiversity, especially in key ecosystem-service providing ...
