In the social wasps, meconium is the fecal waste of the last larval instar before pupation. Meconium is ejected from fifth (last) instar larvae after their last feeding period as a fecal mass in Polistes species. The ejection of the meconium is important for the completion of metamorphosis. The aim of this study was to determine the elemental composition of meconium from Polistes dominulus (Christ) (Hymenoptera: Vespidae). Meconia were analyzed with an energy dispersive x-ray scanning electron microscope where the average atomic percentage of C, N, O, P, K, Si, Fe, Mg, S, Al, Ca, Na, and Cl were determined. We also found that the percentage of elements in the meconia in our study were variable and probably attributable to larval diet. Resumen En las avispas sociales, el meconio es el desperdicio fecal del ultimo estadio larval antes de la pupacion. El meconio se expulsa de las larvas del quinto (ultimo) estadio (instar) despues de su ultimo periodo de alimentacion como una masa fecal en las especies de Polistes. La expulsion del meconio es importante para completar la metamorfosis. El objetivo de este estudio fue determinar la composicion elemental del meconio de Polistes dominulus (Christ) (Hymenoptera: Euminidae). Se analizo el meconio con un microscopio electronico de barrido de rayos X de dispersion de energia donde se determino el porcentaje atomico promedio de C, N, O, P, K, Si, Fe, Mg, S, Al, Ca, Na, y Cl. Tambien encontramos que el porcentaje de elementos en el meconio en nuestro estudio fue variable y probablemente atribuible a la dieta larval.
