Males mostly disperse and leave their home nests, while females have been observed to possess philopatric behavior.

Male genitalia are extremely sclerotized with a distinct gonobase and small to moderately sized upper gonostylus.

[2] Among the genera of Euglossini, Euglossa are known to be especially metallic and glittery and smaller in body size, and E. cordata are no exception, as individuals are observed to be a brilliant green color.

[4] Euglossa cordata have an exclusive neotropical distribution and are spread out throughout the South American region, particularly in Brazil.

Adults have been observed to fly great distances, sometimes more than 50 km, for nectar or floral odors used for sexual attraction.

To leave the nest, an individual creates a small round hole in the resin, big enough for one to pass through.

They will then hover near the flower and scrub their legs together, which then deposits some substance, whether it be pollen or nectar, in their inflated hind tibiae.

Males will pollinate orchids but are also attracted to rotting logs, certain fungi, and other objects found in tropical forests.

[2] Orchids of the subtribe Catasetinae will place their pollinaria on the bee by a trigger mechanism ejects the pollinarium forcefully.

In addition, several genera of the orchid subtribe Stanhopeinae deploy mechanisms, which depends on if the bee slips and falls.

In addition, males also exhibit brushing behavior on rotten wood and infected living trees, as they may be attracted to fungal products.

[5] Although little is known of the mating habits of E. cordata, they have been observed to display behavior consistent with other species of the tribe Euglossini.

E. cordata will visit tubular nectar-rich flowers of the native and introduced species of Apocynaceae, Bignoniaceae, and Convolvulaceae plants.

Female S. bilineolata will open the cells that have been closed by resin and remove E. cordata eggs and larvae.
