During the taxathon carried out in November 2017 at the La Sabana Metropolitan Park, a list of aquatic macroinvertebrates was made, using the taxonomic classification system. Several segments of the lagoon perimeter were sampled using a D-type net and hand strainer (both with 0.5 mm mesh pore), as well as a handnet. All possible microhabitats were reviewed, including hard land banks, muddy banks, grassy banks, cement edges, areas with aquatic plants, vegetation roots, silty bottoms, under rocks or logs, and on the surface of the water. Several of the identified taxa are described. A total of twelve orders were found in the first sampling, distributed in six taxonomic classes of aquatic macroinvertebrates; on the other hand, for the second sampling a total of twelve orders were found, distributed in eight taxonomic classes of macroinvertebrates. The lagoon has a lentic habitat condition, that is, it does not have a circulation process except the effect of the breeze on the surface. This causes their oxygenation conditions to be minimal. Although the diversity found, so far, does not represent a public health hazard, it is necessary to adopt measures to recover said habitat to improve it and the environment. ; Durante el Taxatón realizado en noviembre del 2017 en el Parque Metropolitano La Sabana, se procedió a hacer un listado de macroinvertebrados acuáticos, usando el sistema de clasificación taxonómica. Varios segmentos del perímetro del lago fueron muestreados utilizando una red tipo D y colador de mano (ambos con poro de malla 0.5 mm), así como una redecilla manual. Todos los posibles microhábitats fueron revisados, entre ellos, orillas de tierra dura, orillas fangosas, orillas con pasto, bordes de cemento, zonas con plantas acuáticas, raíces de vegetación, fondos limosos, debajo de rocas o troncos y sobre la superficie del agua. Varios de los taxas identificados son descritos. Se encontraron un total de doce órdenes en el primer muestreo, distribuidos en seis clases taxonómicas de macroinvertebrados ...
