ResumoA mass emergence in August 1977 of the aquatic midge, Siolimyia amazonica Fittkau, is reported in Kendall, Dade County, Florida, near a small canal in a residential area. The species previously was known only from Brazil, Nicaragua, and Peru. Additional records are reported from the Bahamas, Mexico, and the Panama Canal Zone. On Lake Nicaragua mass emergences of this species, called Sayule by the local people, cause a serious nuisance problem. The males possess greatly enlarged genitalia that are inverted, suggesting that the species does not swarm but mates while running around on the substrate. It is problematical whether the species occurs naturally in tropical Florida, or whether it has recently been introduced by commerce; in the latter case it may potentially become a pest species.
