White gives the reference to Olivier’s figure with a 
mark of doubt; but on comparing the description as 
well as the figure, there can be no uncertainty about 
his species being the same. 
It is generally distributed throughout the Amazons, 
and not uncommon in the dry season, at sweet-smelling 
flowers. Like all the other species of these beautifully 
varied and interesting little creatures, it flies nimbly from 
flower to flower, deceiving the eye of the beholder by 
its strong resemblance to a wasp.
