Abstract
Stachytarpheta jamaicensis has been found to have various visitors but its actual pollinator is unknown. I Collected nectar from 22 individual plants during various times of the day and I determined that S. jamaicensis produces most nectar during 6:00 am and 6:00 pm. Observation of the visitors were recorded for each hour and ten flowers were collected for each potential pollinator after they were observed obtaining nectar from the flowers. Nectar production was found to be significantly abundant early morning and late afternoon, this suggests that S. jamaicensis produces nectar for hummingbirds and moths since this is when they are most active. Flowers used in order to determine how much pollen remained on the stamen after visitation by each potential pollinator. Observation of activity and statistical analysis showed that butterflies were the most abundant in visiting, but pollen amounts on the stamens did not show any significance for any of the species. Due to lack of sufficient data on moths, the amount of pollen left over after visitation of these species was unable to be determined. Stachytarpheta jamaicensis ha sido documentada como una especie que atrae diferentes visitantes pero su verdadero polinizador es desconocido. Muestre néctar de 22 plantas individuales durante varias horas del día y determine que S. jamaicensis produce la mayor parte del néctar durante las 6:00am y las 6:00pm. La visita de los polinizadores fue registrada a cada hora, diez flores fueron reunidas para cada uno de los polinizadores potenciales después de que ellos obtuvieran el néctar de las flores.
