[1][2] They are robust brown or black bees, hairy or velvety, and often striped with yellow or orange, typically resembling bumblebees.

[3] Eulaema is found from Rio Grande do Sul (Brazil), Misiones (Argentina) and Paraguay[4] to northern Mexico with occasional strays into the United States.

Scientists use different mixes of scents to study these bees, including eugenol, cineole, vanillin, skatole and methyl salicylate.

After collecting scents, males choose a branch or tree trunk in an area with more open canopy to make their displays.

While Eulaema generally reproduce year-round, local fluctuations in climate affect abundance and activity.
