This study aimed to characterize the occurrence of Stigmacoccus asper Hempel, 1900 (Hemiptera: Coccomorpha: Stigmacoccidae) on Quercus humboldtii Bonpl., 1805 (Fagaceae) within the Civil Society Botanical Gardens Network of Alto Ricaurte, Boyacá, Colombia. The species was recorded in six of the nine sampled zones across three municipalities (Arcabuco, Gachantivá, and Villa de Leyva) at elevations ranging from 2222 to 2656 m a.s.l. A total of 81 individuals were collected, including 76 immatures and 5 adult females. The population was dominated by immatures (mean = 12.7 individuals) and showed low representation of adults (mean = 0.8 individuals). Adult abundance was negatively correlated with altitude and humidity. The findings highlight the ecological relevance of S. asper in Andean oak forest dynamics, emphasizing its trophic role and its potential for sustainable beekeeping and ecosystem conservation.
