again as long as the clearing in the forest still exists. Males repeat cycles of patrolling and perching as long as the male remained in the territory and was not disturbed by other males. Male E. meriana flew about 2-3m from their perch when no males were present, but 4–6 m when other males were within 5m of their perch. Conflicts were sometimes observed, but were 60–90 seconds long. The males would fly around each other until the other male left. It appears that male aggregations are seen at favorable mating sites and is likely not due to males attracting other males. The more suitable sites within a treefall, the larger the number of potential territories, and the more males were found in these areas. Kimsey suggests that this type of a lek is a transitional type of lek in the entire evolution of classical leks. Male-male interactions David W. Roubik of the Smithsonian Tropical Research Institute observed male E. meriana forming a ball around a recently killed male of their species. They were observed to be biting the dead male’s hind tibia and scraping them with their forelegs, a behavior typically seen in their chemical harvesting. Roubik notes this as a sort of chemical parasitism – it is possible that the dead male had a "good" blend of chemicals, and the males scraping them off attempted to gather the potentially favorable blend held by a former competitor. Chemicals stored by the male E. meriana do not change chemical composition over the few weeks they are stored. Other species observed on the Barro Colorado island in Panama had unique chemical combinations. Thus, it is hypothesized that if a male has good survival, and has had good foraging success with orchids, saps, resins, or fungi, it could have a better chance of mating. Female-male interactions Some field observations suggest that male Eulaema meriana collect these volatile fragrances to inform potential mates that they have “good genes”. <ales had the same sweeter mandibular gland odors but very different, rancid hind tibial odors. When a female approaches a male, the male likely disperses collected odors towards the female – it is at this stage that the male would disperse a chemical blend specific to the E. meriana. Males that have lived longer and foraged widely, as evidenced by the chemicals it disperses, could show the female that they are better equipped with “better
