	abstract = {<p>During a four month study of male territoriality males of the euglossine bee Eulaema meriana exhibited the two alternative behavior patterns of territoriality and transiency. Territorial males patrolled an area adjacent to a tree upon which they perched. Territorial males utilized the same territory for up to 49 days, though often not on consecutive days, and appeared to non-violently relinquish territories to new males. Transients did not defend territories but flew from one territory to another and flew with the territorial male around the territory, rarely bumping, and never grappling. Transient males left the territory soon after the territorial male flew back and forth in front of the perch tree in a zig-zag flight. The alternative behaviors were correlated with wing wear such that males with little wing wear defended territories and males with considerable wing wear pursued a transient strategy. Behavior patterns were not correlated with head width. Comparison of territory trees with the territory trees of a closely related species indicate that each species utilized trees of a certain diameter class for perching. In addition, analysis of hemispherical canopy photographs indicates that males appeared to prefer territories that received a maximum of diffuse sunlight but a minimum of direct sunlight. Both territorial and transient males consistently returned to specific territories over their lifetime but appeared to travel long distances to forage for fragrances. Territorial and transient males visited fragrance baits with equal frequency suggesting that non-territorial, as well as territorial, males required fragrances.</p>
