Sequencing data from a mitochondrial gene was unable to separate E. viridissima and E. dilemma, indicating they are closely related and form a clade within Euglossa.

Males of these bees store aromatic compounds extracted from various environmental sources in pouches on their hind legs.

Certain characteristic compounds present as main ingredients in these perfumes in E. dilemma were found to be absent in E. viridissima.

The male has an enlarged joint on his hind leg where there is a pit for storing substances he gathers from plants.

[1] The native range of Euglossa dilemma is in Central America where it extends from Costa Rica to Mexico.

[3] In Florida it is thought to have originated from Mexico and arrived in the state by accident, perhaps being transported in a nest in a wooden structure such as a pallet.

[1] In its native Mexico it is found in hot dry habitats including degraded forests, pastures, parks and gardens.
