Eufriesea

Eufriesea is a genus of euglossine bees. Like all orchid bees, they are restricted to the Neotropics.
All species range from entirely to at least partially metallic (the face and/or tegulae), though much of the body in some species may be brown/black in color and hairy.
Distribution.
"Eufriesea" is the most widely distributed genus of euglossines. Specimens have been found from Mexico to central Argentina.
"E. purpurata".
At least one of its species, "Eufriesea purpurata" from Brazil, has been shown to selectively collect large quantities of the insecticide DDT without any apparent adverse effects. Individual bees were observed to collect as much as 2 mg. The males of orchid bees are known to collect aromatic fragrances from certain kinds of orchids, and it is thought that they use these in territorial display and courtship, probably as precursors of their own pheromones. Some orchid bees have also been found to collect fragrances from rotten wood.
Name.
The genus is named after entomologist Heinrich Friese.
