Explanation of Names
There appear to be two possible origins for the name Hemaris:
1-From the Greek hemera, meaning a day (1), possibly referring to the day-flying habits (PDF factsheet on Hemaris tityus, a European species).
2-From the Greek root haem, meaning blood. North American species of Hemaris were originally placed in the genus Haemorrhagia Grote (2), clearly from the root haem. This suggests some sort of relationship, though the spelling, one would think, should have been something like haemaris!
