Danau Tangkas is a conducive habitat for dragonfly breeding because the habitat conditions around Danau Tangkas are still beautiful with preserved vegetation. However, the Danau Tangkas area is a tourist area, so it has the potential to experience changes that can have an impact on the dragonfly dominance index. The study aims to analyze the dominance of dragonflies found in the Danau Tangkas natural tourism area. The type of research is exploratory descriptive research.

Made 3 stations with a length of 100 m each to the side and 100 m to the front so as to form a square line. Sample collection is done by hand collecting and using insect nets. Data analysis techniques using Simpson's dominance index calculation. The results of research that has been carried out in the Danau Tangkas natural tourism area, obtained as many as 447 individuals, 9 species belonging to 3 families.
