Male euglossine bees were captured monthly for one year in modified McPhail traps baited with cineole, methyl salicylate, and skacole. The traps were operated 90 km north of Manaus, Brazil in continuous terra firme forest and forest fragments of 1, 10, and 100 ha. Of the 16 species of euglossine bees captured, Euglossa chalybeata and Eg. stilbonota accounted for 85 percent. The traps had the advantage of operating unattended, but their capture efficiency was low. Bee abundance and species richness were significantly correlated and peaked in the wet season when flowering also peaked. Contrary to a previous study in the same area, bee abundance was greater in 10-and 100-ha fragments than in continuous forest. Fragments of 1 ha had the smallest number of individuals and species. It appears that male euglossine abundance may vary considerably over short distances, making it difficult to characterize a forest by sampling a single site.
